[Q] How does the car dock work? - EVO 4G Accessories

I have an existing car dock (just a holder) and usb cable. How can I trick my evo into thinking it is plugged into a car dock? Is it magnet based?

I don't think it's magnet based, but I think there's a circuit board in the bottom of the official car dock that tells the EVO when it's plugged into that, it's in THE offical car dock (I have one)

The Seidio car dock triggers Car Mode as well. I thought someone posted about it being magnet-based, but I could be wrong.

I think it's done through pins 4 and 5.

Q how do I make a homemade car dock cable for HTC EVO

question is are there any videos out that have a walk-though for making a cable that will put the phone into car mode
ok i could be wrong on this so dont shoot me. It is my udnerstanding that it isnt the cable that puts it into car dock mode for te evo. it is a magnetic band on the dock itself. As an alternative since i have only heard of the official HTC cardock acctually putting it into car dock mode (it doesnt come with a cable) you can get a cardock app to put it in. yes it is an extra few buttons but it may be your best bet.
Its nothing with magnets. On YouTube someone quickly explained about jumping pins together but was hoping for alittle more depth

You are looking for a USB OTG cable... You can make one of your own connecting Pin 5 to ground.

[Q] Desktop Dock w/ Speakers?

I've tried searching Google up and down, but there doesn't seem to be a dock with speakers for the Glacier anywhere. I would be perfectly fine with a dock that I can just plug in to some speakers, but the OEM dock uses the USB port and not the pins, and I rather not mess up my USB port trying to get the phone in and out of the dock. Does anyone have any recommendations for a dock, or am I SOL?

[Q] GS2 car dock plug for Nexus?

So I just bought the GSM galaxy nexus from the play store (waiting to be shipped). I am seeing all of these car dock issues not having the POGO ect. My Epic 4G touch car dock uses the USB for music and charging (AUX and chargers plugs in back). Does anyone know if the usb with these types of docks will plug into other phones like this one and still get sound and power from the Dock? If so it might be worth looking into a mod? Just curious if this has already been discussed?
im sure it would work just fine if you managed to mod it precisely. personally i felt like the dock caused some wear on the usb port which is y i loved the idea of the pogo pins.

HOWTO - Enabling native Car mode

TL;DR: 10kOhm between ID and GND
Hi,
I just posted a Kidigi car dock fixed, and also investigated how car mode is enabled.
On previous devices I had, car mode was enabled by a small magnet in the dock, which triggered car dock (Motorola devices use this).
On HOX, this is enabled by puttin a 10kOhm resistor between GND and ID pins (they are adjacent).
Somebody could investigate what other resistances do - there will be at least a dock mode as well (I only tried that it is not activated by shorting those pins).
So if you want to make your car cradle activate car mode, you can mod your cable and get the full functionality of the original overpriced HTC @#$%.

[MOD] Car mode USB cable resistance value

Hey guys,
i just bought a passiv car cradle for my GN. I need the car mode and doesn't finde anything about the resistor value between the micro pin 4 and 5.
While searching for it, i just had that value for the galaxy s i900. But the 620kΩ resistor doesn't work for the GN.
Am I wrong with the resistor? Is there another method to get into the car mode?

Download a car home app and run the app.
There is no microusb car dock for the nexus, only a pogo pin car dock.
