Using MTCB with rear entertainment system. - MTCB Android Head Units Q&A

My Jeep has a VES or Video Entertainment System in the rear. I have a CANBUS adapter that I installed my Joying HU with and everything works. The VES still works with the wireless headphones, but is it possible to get it to work through the HU and play through the speakers like the OEM radio did? The factory radio had a source selection, but I'm not sure if it's possible to do something like that with these MTCB units.

what kind of Jeep? I am not sure, but I think the VES will only work with a DVD in the Head Unit.

Jeep Commander. It has a separate player in the center console for the dvd's.

another user on here has a Jeep Commander with the VES, pretty sure he couldn't get it to work. Search for "Jeep" and his posts should show up, pyrie or something like that was his username

Do you mean get videos to play to rear monitors ? If so, then the only way is if you have a unit with a DVD player built in, then you can, but ONLY from the DVD, no other source.

Yes and yes. I have the commander with the Eanon GA2114. Ves will work but you need to do some work . My VES was originally connected to a REC nav unit. The back of the stock jeep rear video entertainment unit has a wiring schematic. Just splice appropriately

How do you select it? Like once you play the DVD, how do you select the source from the headunit?

Also, did you use a CANBUS adapter?

Yes I'm using the pac rp4-ch11 canbus adapter. I have the stock Boston acoustic premium audio and this canbus adapter supports the stock amp and steering wheel controls. You select the AV input to pass the VES video / audio into the head unit.

The AVIN app you're speaking of?

I'm not sure about your head unit, but as you can see by the schematics of mine I have an audio video input that I connected my VES unit into. From there if you look at the other attached photo, there is an AVIN in the upper right hand corner that you would have to select in order to choose the video / audio input channel on the back of the unit. That is how mine is connected.

[Q] Connect WP7 to Car Stereo via USB?

I would like to purchase a new cd head unit for my car and use my Zune Pass on my WP7 device to play all my music via USB.
Why USB and not 3.5mm aux cable?
1 usb cable vs 1 usb cable + 1 aux cable
I would like to be able to charge my WP7 device and control volume/play/pause/etc from the car CD head unit rather than my WP7 device
1. Has anyone tried this or have another method to get this to work?
2. How is the quality of streaming music over bluetooth?
After searching the forums I found this post related to the galaxy s:
http://forum.xda-developers.com/showthread.php?t=726403&highlight=cz509
thanks
you cannot use usb and streaming music on any platform.
When you use a usb connector, then you are using your phone as usb storage device, that is why you control music from the head unit. This is not possible currently on wp7 since you cannot use your phone connected to a computer without zune installed.
The post you linked was for BT audio out, which works the same as the 3.5 jack, not usb.
any comments on the quality of BT audio out?

I use the the 3.5 jack.
I thought about BT audio but so many people have had trouble with winmo and Bt that I didn't want to spend 150.00 for the module to find out it didn't work.
3.5 - RCA cable....
Thats the best way to do it... Most car head units have an RCA AUX IN on the back.
Attach the the 3.5 - RCA cable to the head unit via the RCA and plug in a 3.5 - 3.5 cable to the phone.
Thats what I'm doing now....
It's in fact the BEST way to get the most out of the audio decoder as it goes from the phone - amp - speakers/sub, so the phone can be on low imput *best way* and the amp does all the work making it sound wonderful.
here is a pic of the one cable solution...

or the smaller version i have that i just plug in the extra cable from the glove box when i need it as the end just pops out from under the head unit with no long cables to hide.
bluetooth
bluetooth stereo is the best way to go i've been using it since windows mobile. sound quality is very good i don't notice the difference with aux cable but i have one in my car for my zune. with bluetooth you can control simple actions like you would on your phone like change tracks and volume and mine can also make calls and it shows you the name of the person calling you in the stereo lcd

Bluetooth audio streaming accessory

So I get my S2 tomorrow (Giddy as a schoolgirl) but I was looking for suggestions on replacing my current audio streaming setup. Basically my current phone, the Nexus One, had a bluetooth dock which when paired (Either when physically in the dock or over bluetooth) it would stream all audio from the handset to my connected sound system (Via 3.5mm jack).
I'm looking for an easy way to do the same with my S2, I don't really use the actual dock for physically docking so if there is a different/cheaper alternative which achieves the same effect then I'd be more than willing to try.
Thanks
If I understand what you are saying right then this here is what I am using and I find it superb.

Wondering why your existing dock won't work with the SGSII? If its bluetooth it will be handling streaming over the A2DP bluetooth protocol, which the SGSII supports, I doubt there is anything Nexus specific about it...

I want that but with a 3.5mm input jack rather than the cable coming out from it. I'm basically looking for some sort of bluetooth hub/headset which has a 3.5mm port. I know I didn't explain it very clearly

Unfortunately it's the official Nexus One dock and can only be paired once the phone has been docked once, therefore it only works with Nexus Ones. PITA for sure
Ah, OK, thanks for that explanation.
I have this - http://www.sonystyle.com/webapp/wcs...51&storeId=10151&langId=-1&partNumber=DRCBT15
Very nice as a receiver, but also good for use with whichever headset you like (I use it when exercising, the AVRCP controls are very handy for controlled media playback).

That's exactly what I'm looking for, it's really helped push me in the right direction. Cheers
I am not sure able DRC-BT15 since I didn't brought this one. But I would suggest Sony's DS-220 or DS-205, those two unlike the newest MW-600 could be use under charging. (I own all of them...)
I've got a Jabra Clipper which works quite well. Just leave it plugged in to the plug and the stereo all the time.
If your stereo has an iPod dock you can try the uPlay bluetooth dock adapter - sadly didn't work with mine, suspect it's because my stereo tries to be clever and offer controls as well as just music playing.
There's also a Belkin dongle but I've never used it.
Any other solutions you find primarily aimed at home use rather than a repurposed portable one, I'd be very interested
I use this, the HP Bluetooth Pendant. It's a transmitter and a receiver. You're looking for the receiver (bottom part of the picture). The transmitter's pretty cool if you want to use a pair of decent wired headsets over Bluetooth. It's discontinued but you can still find them online. The model number is KD031AA#ABA.

IPhone headset works on Nexus?

Hello,
I am searching for a new pair of reasonable quality earphones for my nexus.
The main goal is to use them to listen to music and the occasional videos.
It word also be nice if they had a mic to be able to use the earphones in phone calls too.
So, does an earphone with mic for the iphone like the DREX300IPB from Sony work with the nexus?
Thanks.
Cheers.

are there 3 rings on the 3.5mm jack? if so, the mic should work.

I think so. I will have to go to a store and check.
There are also models for iPhone with controls to stop/play, forward/reverse, mic and such.
Do does work with android?

Doubt all the multimedia buttons will work, but you just have to try
Swype'ed on my CM10 Galaxy Nexus
The answer is yes.
However, volume buttons don't work, but the calling/play control button works.

There are 2 standards that exist, iPhone headset, and standard mobile phone headset with in line mic which 99% of phones support. Nexus supports the normal standard, not the iPhone standard. Just buy the standard one.
Example, Bose MIE2 or Bose MIE2i. There is always both options. Just buy the right one.

Thank you for the explanation.
However, I seem to find far more models with mic and controls that say that are made for idevices. The choice seems to be greater and so I was wondering of they would work at all on the nexus.

Just one more question.
Do the beats by Dre for HTC sensation work on the nexus? The Mic and the play controls?

Evo and stereo bluetooth hdmi usb video?

Hi.
I just installed a boss 7" touchscreen stereo on my car. It has bluetooth usb and all the good stuff.
After playing around with it i started thinking if there is a way to stream video from my phone( like hdmiteam win app) using the aux cable. What i mean is, there is a function on iPod settings that changes to TV out using the headphone jack.
Is there anything similar for evo?
Another question, have u guys used the usb-to-hdmi converters?
I was thinking on buying one to see if i can stream video using that, if there us nothing like what u mentioned above.
Thanks guys, any input or ideas would be awesome.

There is not a way to stream over the headphone jack that I know of. Also the usb to hdmi is not an option either. Our evo does have a micro hdmi out that does work to stream audio and video. It will work with any hdmi input. The cable can be found online for less than $5. I have purchased one myself and use it for Netflix on my led tv. It works great as long as your rom supportys hdmi out.

Right.
The ipods audio jack and it's cable are specifically specially designed for video output unlike our evos 3.5mm jack which is not.
What type of video inputs does the display on your touchscreen car stereo have?

Here is a picture of the back of your stereo.
It has an HDMI jack right there.
Output the same way you would to a TV with the same HDMI to Micro HDMI cable.
(You'll have to run the HDMI cable from the back of the stereo to a spot you can plug in your phone.)
That is actually a usb jack and not hdmi. Thats why i was thinking of usb to hdmi coverter.

Ah, damn.
Try a Composite to HDMI box.
http://www.amazon.com/gp/aw/d/B0080KN18K/ref=mw_dp_mpd?pd=1&qid=1363125109&sr=8-1
Should work, check with the manufacturer to be sure.
It would be
Evo<HDMI<Box<Composite<Stereo
Ok. I ordered one, one of the reviews said it used it for his droid and stereo so im guessin it should work.
Ill keep this updated

Distortion on RCA out

Hi,
I know the MTCE are not known for their sound quality but anybody have distortion on RCA level out? Even set the gain at the amplifier to minimum I get distortion when the volume slider goes higher than 20.
Why is that? I also feel like frequency response sucks on the RCA.
Is speaker level better from your experience?
Will a line driver help in this case?
Thank you for your time!
Laurent
Maybe your rca s are like mine and have a groundloop.
If your amp has highlevel input, id try using them
Had the same issue. Went with a AudioSource Matrix Line driver that definitely helped a lot in Sound Quality. Not where I wanted, after the line driver there was still a little noise so I got noise filters and gone (ground loop isolators are the same thing). Noise was gone but sound was not there completely. So I went with a JBL DSP. night and day. So clean coming from a crappy Android Unit. lol. I dont care what anyone says. these android units are the best way to go. Just need to beef them up at the outputs to get them sounding amazing.
What do you mean by a "JBL DSP"? Is it a JBL Amp with DSP capabilities or just a straight DSP? Are you still using the RCA line-level outputs or did you end up using the speaker-level outputs?
Thanks.

Stand alone DSP.. I went with Audio Control Matrix to JBL Stand alone DSP. I used the RCA's but some noise filter on my single input to the line driver and then used the line driver to convert the signal since my line driver is also an EQ.. One (front) input and pushes my three outputs (Front, Rear and Sub). Sounds great but I recommend doing all three inputs and outputs. It boosts sound quality. I am waiting another set of interconnects to change from single input to three inputs.
Ok, thanks for the clarification. I gave up completely on my Eonon-branded Android 8 MTCE unit. Between the noise-related issues and the overall sound quality, I just wasn't happy with it. The WinCE unit I was coming from (Dynavin N7) just sounds *considerably* better, even when using the same external Kicker auto-tuning DSP amp and all of the same wiring in the car. So I've re-installed the WinCE unit and will use the Eonon for another project (creating a portable wooden "boombox" with the Eonon as the main "control center" and some component speakers I had laying around. Should make a nice portable do-it-all, touchscreen Android "media center".
