My Tbolt Car Mount Install Acura MDX

I just wanted to share my car install experience. Notice that I only used the holder portion of the mount, and I cannot swivel to landscape mode. This works for me since I already have built in Acura navigation, and I mainly use my Tbolt for streaming MOG radio which is portrait mode only. This install location works perfectly for lack of glare, cable placement, accessibility, and allows me to keep my focus on the road.
** note: I used an agressive mounting tape capable of holding up to 5lbs and dealing with high temperatures. This is available at Home Depot in the paint department for $4. I mounted the car holder directly to the fake black wood panel that has a glass finish gloss surface. PLEASE do-not blame me if you ruin the $95 panel should removal cause the fake wood to crack, etc.
1- The car mount is at Verizon stores & online part # HTC6400MNT for $29.
2- The micro USB port on the mount has two metal dimples that are evil and require WAY too much force to install & remove the Thunderbolt. I recommend using a single edge flat xacto blade to remove as much of the dimples as possible. Once removed the Thunderbolt slides on and off the mount properly.
3- ******* Before mounting!!! Attach the micro USB power cable & route the audio cable and choose a location that allows the mount to remain flat against the surface & gives the audio cable enough play to be connected & removed.
4- Prep both surfaces with alcohol to remove any surface contaminants.
5- Remove the double side adhesive mounting tape covering and carefully align and lightly press the mount on ONE tiny leading edge only... allowing you to slightly adjust alignment prior to fully pressing the mount into place. **It's strong adhesive and you only get one shot so be careful.
This process has worked perfectly for my needs, and the mount is rock solid. I have a full view of the screen from my seating position, easy reach to the display, and as much as I wish the micro USB port on the mount passed audio.. it's really not a big deal dealing with the audio plug.
I hope this helps and streaming 320Kbs from MOG's 10 million database of music over 4G is such a thrill. They currently have a major Android player bug but an update will release soon.

Wow.. looks good!

Dude MOG on Android has sucked since day 1. Hopefully they will get it straightened out one of these days, I gave up.
Nice job - looks very similar to mine except I went horizontal down by the AC controls (Explorer) and switched to the Google Car Home - it is sweet. I like the 90 degree cable - where is it from?

I got very lucky and found this at Radio Shack... even the inept sales guy kept saying it didn't exist... then I located exactly what I needed on his rack It might be easier to find it online & get it shipped. If I can pull the package out of the trash I'll replay to this thread with the Radio Shack part number.
The clearance between the car mount plastic & the 3.5mm jack of the Thunderbolt is very tight. Fortunately this cable has a thinner section closer to the base of the metal jack allowing it to clear the plastic of the mount.

It's the one made by Google, it's the best - very customizable. You won't be able to find it via market on your phone since it is "incompatible" because of stupid sense. Just download the apk and side load via USB or dropbox. when you choose the car panel app it will prompt you for which app to use - choose the Google one and set to default. Then when you put the bolt in the dock, it will launch google car home.

Thanks I'll track one down. I have a regular coil cord but want to hide the aux cable like I did with the power cable. Plus it sticks out just enough to hit my knee - the 90 degree will do the trick though.

No matter what phone dock I get, I always adapt it to a vehicle specific mount. I hate suction cups and vent mounts

I have my set up nearly the same only in the left bottom corner of my windsheild... I long ago hard wired a dual cigarette charge port to the inside of my dash and have routed power to a couple differnet devices and places using standard car chargers and makes the install seemless...
The next step in my install is to find a 4 conductor 3.5mm male to 2 female 3.5mm adapter or make one myself (one mono and one stereo on the female ends) and hardwire that to a mic element I have and the rear aux input of my car stereo... hopefully this setup will yeild much better speech recognition and usable docked speakerphone calls without buying an expensive bluetooth setup.

nice looking setup

I'm thinking about getting this mount.... What's your thoughts OP? Can you charge the phone? Looks like the bracing covers the USB input.

Kudos for a job well done!

Definitely saving this thread. That's a genius idea. I'll be doing the same with my car soon I'm sure.

Hi Guys,
Excuse my brief hijacking of the thread, but I feel this relates to the discussion.
I have recently released a new media player for Android, and the focus is on easy browsing, huge album art and a "no-look" playing screen that let's you control the functions with gestures. There is even an option to keep the screen on if connected to power. Works great in the car.
It's called simplePLAY, and you can see it running on my Thunderbolt here:

Car dock questions

For anyone that owns the car dock:
1) how's the quality? Is it nice? Or is it a cheapo peice of junk?
2) how does it charge the phone? Via cigarette lighter? Or does it not charge the phone?
3) if I wanted to listen to music, does it come with/turn into an FM transmitter? Or do I just plug it into the auxiliary port on my car?
Thanks!

I can speak to the Moto version, it's the one I have. There's an AT&T branded one also. Moto version comes with a USB connection from the dock to a dual USB cigarette lighter charger. At the charger end of the USB plug, there's a short pigtail female aux jack that can plug directly to a 1/8" stereo aux cable to go to your 1/8" aux jack in your stereo (comes with cable also). It charges well, except when the battery gets hot. It tends to do that in direct sunlight unless you blow a/c on it. I would suggest looking at a vent clip for it, that's my plan. This would most likely work with it: http://www.amazon.com/gp/product/B0015A6YN6/ref=ox_sc_act_title_2?ie=UTF8&m=ATVPDKIKX0DER

Yep, USB plugs into the back in that square indent. It wasn't a thorough review.

I got the ATT one and that one does not come with a charger. It comes with the usb/aux cable and dock. I got a rocketfish 2 AMP charger and it works great for it. Charging is great other than when it gets really hot in the sun (all black interior)
The new car dock 2.3.4 software is great and looks better than the earlier 2.2.2 and via AUX the sound quality is great on spotify / slacker / FLAC's and and mp3's into my stereo. I have my mounted near my gearbox and can easily tap what I want while shifting.
Work the money... I think all docks are worth it if it works into your day to day usage.

Thanks guys. Planning on buying this now I've got the Motorola Car Charger from Amazon, so not having a charger come with it is okay for me.

I've heard the dock doesn't work with many cases, so I want to build my own, but the split cable is the most important part. Does anyone know where I can get one, or even which wires are set to which pins? I could solder up my own if I had to, but would need to know what I was supposed to end up with first.

You can get the official Moto case on cnn.cn then by removing the insert from th dock you get a perfect fit. There is a thread on it: Ruggedized Battery Cover.

just to chime in
I have the moto version purchased thru att for $25. The dock works great plugged into the aux on my car. I've even used it to take calls handsfree through my car's stereo (have to turn the volume down on the phone pretty low for best results). The suction cup works well and holds it tight, I use it on my bike as well for bluetooth to my SENA SMH10 on my helmet.

I went ahead and purchased the phone through AT&T and used the 25% off discount for a steal at $29 plus two day free shipping.

thanx!! jj
but it's doesn't work , for some reason when we upgrade to gb we loose control volume thru usb the same as car dock use it

I also noticed that the only control the volume rocker has over the phone when docked in the car is either on or off. This is not good for me, I used the phone through car speakers and can not control the volume from the phone. This makes the calls distorted...

Sounds like you are running a customized ROM with the wake on volume mod. The car dock application runs on top of the standby / lock screen, so my guess is that the volume rocker has been hijacked by the mod, preventing the volume from being able to control the volume when locked and car dock app active. I think gingerbread has a way to go still which is why I am still on Froyo.

I believe this is correct, and I agree fully on the gb thing. I want to put it on my phone so bad, but something keeps telling me to wait. I even dl'd the ninja rom over the weekend and have the zip sitting there looking at me... tempting me...
Anyway, I have the car dock. When you can use it it's awesome. The only issue I had was on a long trip the battery was only at 70% when I arrived. I think the software lets it charge until it's full, then just stops charging at all. Not sure though, and the phone was VERY hot when I arrived too. The body glove case only kind of fits, the top won't clip down with it on. I bought the moto rugged battery cover from cnn, and it fits fine with the insert removed, but I hate the case. Barely any protection on the screen at all. The sides pull back very easily. Like if you are talking on the phone and have your finger on the lower corner, it just pulls off and you have to put your finger on the menu button to hold the phone. It sucks and I went back to the body glove. I don't use the car dock every day, so when I do I just take the case off.

Cardock app not launching
I got the car dock from AT&T. When I put the phone in, it charges fine but the car dock application does not launch. I've tried few different chargers and all possible variations of connecting things in with the same result.
If I manually launch the car dock application, the screen goes back to sleep after some time.
Do I have a defective piece?

The screen will go to sleep and lock if you don't have a power source connected. I have not tested on gingerbread and there may be new issues.

Official Vehicle Dock Kit

Hi all.
Just took delivery of my dock kit, and it's very nice. Well built, but whether its worth £35 quid is another story.
Anyway, that aside...
When the default "Driving Menu" is enabled, is there a way to change it, especially to use CoPilot instead of Google navigation?
I have had a quick search in this section to see if anyone else asked the same question.

Im in the same boat. It would be nice if someone could do a workaround. Nice bit of kit for the price.

How do you get audio to come out of the rear connector. I plugged my 3.5mm cable into the socket and the sound still comes out the speaker!
Have you tried it?

Yep! I should have read the booklet, it did tell me in there ;-)
RTFM!

I struggle to take the phone out cleanly using on hand - always hit the power button. Dock mode seems pretty poor to me, seems to get all voice activated with road noise - is the google one any better? (we have a samsung 'special', I think?)

Another thing I've noticed is the terrible engine whine from the loudspeakers when its charging.
Now I tried headphone out socket too, and the same problem occurs.
To me it's a lovely piece of kit, but if you have it connect via Aux then u need to listen to the whinning noise from the charging.

Anyone conquered the noise suppression from an in car charger? It's doing my head in!

have you checked it's not your car? Will try and remember to test if mine does this...

i also have the whining problem when charging. after some investigation, it appears to be caused by poor connections. in my case i suspect the head unit, as i didn't connect the rod at the back to the car frame with the bolt and nut.
you can get a ground loop isolator for about £15, but they just mask the problem - should really get it fixed if there is an electrical problem

Interesting. I have a 2008 Ford Mondeo from new. I'd hope that is electrically correct, but who knows.
I am awaiting delivery of a new car (Audi A3), so I will see if this has the same issue.
It's a real shame because the AUX out on the device increases the volume limit sent to the head unit and it makes a massive difference all round, this limit set by the poxy EU rules on the headphone out socket of the phone is really low (83% of max volume) and when you compare the two on the device its obvious the car kit is better.
BTW it makes the whining noise out of the headphone socket too, when plugged into cradle.

from what i've read, the noise when charging is usually from the alternator. do you notice the whine change when you speed up. if so, i'd get it checked out.
There is a method of basically powering the head unit direct from the battery, bypassing all the other connections and wires the juice has to go through to get to the head unit. probably what i will do if mine doesn't work after i've installed it properly.

I plugged mine into the radio today. From the headphone socket, no problem apart from a lack of volume (even on max gain, it is only just loud enough against the road noise). No background noise though.
Plugged into the connector on hte back of the dock is a completely different story. A ~10khz whine, which is present even with the 12V lead disconnected, and worse when it is connected. Sounds like breakthrough from a switch-mode power supply to me. Makes the audio-out on the dock not fit for purpose. Time to add my review on a fre sites selling them...
The other complaint I have is that it doesn't grip well enough to the windscreen.

I agree, although I get noise from the headphone socket when in the cradle and charging.
I have raised a returns to send my unit back for a refund. It's a waste of time having it if you cant listen to music on it! Imagine listening to the SatNav with all that silence and "whine" on the speakers, it would drive you bonkers.
It's a real shame as the overall quality is pretty good, but it is not fit for purpose in my opinion.
Will update this thread if I get any more news.

Just posting a review on Amazon... found this review too

This review is from: Samsung Vehicle Dock Kit for Galaxy S II (Electronics)
For the price, this does not do well enough. Yes it fits well, and holds the phone, with an integrated dock connector. However:
It is a push-fit corner grabbing design, and I find it almost impossible to release the phone with one hand.
The windscreen suction mount is feeble, so maybe 20% of the time rather than removing the phone, I end up with the whole thing coming un-stuck.
Dock mode on this phone is almost useless, so plan on replacing it if you think it is a good feature.
The audio-out functions, but there is a very poor electrical design - even if the charger is not plugged in, the signal picks up a constant high pitched whine (even with the car engine off)
Buy a cheaper one, and you'll feel less hard done by.

Hilarious, just posted your comment on here from Amazon, didnt realise it was you until after I posted it!

There's one more for you to find - and it's not a cut'n'paste... Maybe not live yet.

If you don't want to run a car Samsung's menu
If you don't want to run a car Samsung's menu install aps from the store :
Dock No-Op .
If you want to restore the default you have to uninstall the application.
Samsung Cars Menu and that sucks and this increased volume of system sounds, it's up scares. I think everybody can hear it in the around car
And what this menu is, and so one can make your own card to use in the car.
Personally, I mounted the Launcher 7 menu that conforms to the Windows Mobile 7 and has the icon in the system ankles. Cubes as they rotate with the vertical grip twist at the best level for navigation. This arrangement works well in the car, because after docking nothing changes and I can continue listening to your music on the equipment in the car, not a hundred times to click to activate the music listened to on headphones before
Sorry for bad english, but google translator

I was a bit apprehensive about buying this dock as I'd read a lot of reviews complaining about engine noise and sub-par audio quality when outputting sound through the line-out but since receiving it I've been really pleased with it. There is no engine noise or unwanted sounds so I guess this varies from car to car and depends on how your stereo is wired up. I've also run a few low frequency speaker test mp3s through the line-out and headphone-out it as I'd read reports of the line-out cutting off some of the low frequencies but to my ear I hear no different and I get a good response from my sub with both. My only gripe is that the call audio is not routed through the line out. Although I knew this was the case prior to buying, I just can't understand why Samsung would have left this feature out. I've read that this was the case with other Samsung phone's official docks previously and in most of the cases I've read about a solution has been found either through a OS/kernel tweak or an app which sorts the problem out. I'm just hopeful that a helpful dev is able to have a look at this and see if a solution can be found for the SGS2. Otherwise it's a great dock

I have to say I am disappointed with this dock. Coming from a Moto Atrix dock, this is poorly designed. Love my phone, hate the dock.
At first glance it seems extremely well made but after using for a while it is fustrating.
One, they use to many materials compared to the Atrix dock. This thing is huge.
Two, its hard to get out of the dock. The atrix dock had a nice flip up latch that secured the phone.
Three, you have to run two cables from the dock for changing and audio. The atrix dock had one cable coming from the dock with an audio out dongle near the end of the cable.
Last, the freaking background noise is terrible. Dont even try to listen to audio at a low volume.
I like the flip up charger adapter. Also it works with the official extended battery. But thats about it.

[VZW] My vzw g-nex car dock review

So, on my way to work this morning I was in my car fiddling with my phone while driving. Yes, I know i'm not supposed to and it's dangerous! But god damnit i'm used to having a car dock. Its not my fault vzw decided to release this...how should I put it big piece of fecal matter into the market.
Okay so long story short, I almost got in an accident because i was trying to switch songs in google music but b/c i have no car dock, I had to look down. I've lived the past 2 years with my og droid with the car dock. I really wanted to wait for something better, cause honestly without the 3 pin function built into the dock, i didn't want to spend this money. But i finally gave in due to my safety, and the safety of others.
Now here is my review:
Ill start with the good.
-The dock is extremely sturdy. I think once the phone is put into the holder, it will honestly never come out as long as you've secured the base correctly.
-The material that surrounds the phone is very nice
-It's easy to move the phone while its in the dock. meaning lets say my passenger wants to have a look and fool around with the dock, she or he can easily just pop that screen facing his / her way and tighten the bolt.
-It fits with the extended battery
Now the bad:
-This one is obvious. No 3 pin connection????? WTF ARE YOU THINKING VERIZON.
-The phone takes FORCE to put into the dock, and I mean with both hands. I am so gentle with my g-nex usually.... its almost like im molesting it trying to get it in the dock.
-NO charge / audio out on the base of the dock. Again i say, WTF ARE YOU THINKING VERIZON
-The part of the dock that surrounds the 3.5mm audio out jack DOESNT FIT bigger cables. Meaning, if you spent extra money to buy a good 3.5mm cable thats thick, it probably wont fit. I have a belkin pure a/v 3.5mm cable and it does not fit. Most likely will only fit regular sized 3.5mm cables
-Because the dock material is kind of...like rubber i guess? When you forcefully slide the phone in(you have to) it makes me paranoid about the volume / power buttons. To me, it feels like over 100 slide-ins, the keys would probably get damaged because of the force you need to use and how tight the dock fits.
Honestly, if the dock just had the 3 pin connection for audio out / charge i would rate the dock 10/10 for that alone. But because it doesnt, im giving it a rating of 3/10. I bought a gnex for the sole purpose of utilizing those 3 pins so i dont have to plug **** in every damn time i get in and out of the car. But for now, it serves its purpose as purely a phone holder.

Can you confirm that a car dock app doesn't pop up automatically? I use Car Dashboard Pro.

I can confirm...since it is merely a place to put a phone with no automatic port to plug into it technically doesn't even know it is in a dock.

I completely agree with your review--I ended up picking it up, strictly because I needed nav on a road trip...but still not happy about having to buy this thing.
Have you guys checked out the reviews for this thing on the Verizon site? All of the reviews are 1/5 or 2/5 stars (first review by yours truly)...yet somehow the overall rating is 5/5. Verizon should learn how to cheat at product ratings less obviously...

Phillips Fidelio

http://www.londondrugs.com/Cultures...lack - AS11137&ProductID=5354873&ProductTab=3
Just thought I'd post to say I've tried this Phillips Fidelio Alarm Clock/Charging station/ Bluetooth speaker system.
My impressions are pretty good with it. The speakers are not amazing, but good enough for a bedroom use which it's intended for. It plays music via bluetooth and has an application that you install with it such that the bluetooth will turn on once you plug the phone in. It will automoatically revert back to your normal bluetooth settings once you remove the phone.
For the price of this system, it's cheaper than me buying a charging dock from samsung. Also, I'll be able to use it for future devices as the bottom slides to adjust for phones with the charging plug mounted on the side.

I have it too, and I like it. Their Fidelio app seems to work acceptably with the Galaxy Nexus. It's also possible to use Tasker to have a "nightstand" mode (based on charging and being connected via Bluetooth) if you want more customization.
When the phone is docked, it shows up as charging via USB, not AC. I assume that means it can only draw 500 mA of current. I don't mind this (I normally leave it docked long enough to charge fully, and I'd rather it charge slowly anyway since that's likely easier on the battery.)
The main annoyance I have with it is that the speaker makes a "boop boop" noise when it connects or disconnects via Bluetooth, so if my wife's already asleep, plugging the phone in will risk waking her up.
I use my phone without a case, but I would think that this dock probably would still work with the phone in a case as long as it's not too thick on the bottom.

The bottom of the mount has a couple of adjustment screws to adjust to different thickness bases in case you have a case on the phone.

Yep, so they should accommodate most any reasonable case. They do, however, hold the phone by the bottom and therefore render the headphone jack inaccessible if you wanted to use it for some reason.
