Yukon 12 Denali Chinese android unit

[beeswax]

Hello everyone!

I have a 2012 Yukon Denali with the OEM Bose system, and I recently bought a Chinese Android radio that was advertised as plug-and-play. Most features are working fine, including the OEM camera, door notifications, and automatic switching to the backup camera when in reverse. However, the audio isn't working.

I contacted the store multiple times, but the customer service reps weren’t very technical and couldn’t help me solve the issue.

After going through some forums, I found out that the OEM amplifier requires a specific signal to turn on. The wiring harness for the unit has a single disconnected wire labeled "amp cont," but I can't figure out where it should be connected.

Has anyone here dealt with these Android units before and can offer some advice? I bought the screen from AliExpress, and returning it would cost more than the price of the unit itself.

Thanks in advance!

This absolutely drives me crazy that its totally designed to be not financially returnable and that installation instructions are not vetted before being put up for sale. Good luck, I had a similar experience with a radio I ended up returning for one I bought from crutchfield (which I also don't love).

If I am reading the wiring schematics correctly it looks like connector C1 is a Black connector on the back of original radio and that would be Pin 6 which should be a White wire which is "Remote Enable Signal" to amplifier.

This is assuming you don't have RPO Y91 on the RPO sticker in your glove.

Yeah exactly, this has been going for sometime now and they have 0 installation instructions. To be fair they sent me 2 sets of wires stating that it will fix my issue with no luck. I read everywhere that Crutchfield is the best go to regarding head units but unfortunately I can't order to my country.

I do have the RPO Y91 on the sticker, what does it mean?

It means you have the "Smart" amp, you can tell because it will have a speaker in the center of the dash. The "Dumb" amp system doesn't have the center speaker.

I believe on the smart amp it is turned on using data over the canbus system. But I may be wrong as I don't have that system.

Finally, the issue is fixed. There is an AMP control line that goes out from the RCA cables, which is usually colored blue. It should be connected to a wire on the CAN bus (in my wiring harness, it's colored green).

This is my final result:

Thank you!

What head unit did you buy?

Hey is there a wire on the canbus that controls the rear camera? I got that radio and can't get my oem camera to work with adapter. You earlier post helped me fix my sound issue after almost sending this unit to it's maker lol

Thanks for this! Was struggling with this exact issue as I was trying to swap my head unit last night. So you just spliced the amp-con(trol) from the head unit onto that green wire from the CAN bus connector? Going to give that a shot today.

Still no luck, not sure what I've got wrong but it's clearly something

FWIW The OP hasn't been on here since April.

The AMP-CON wire is coming from the Android’s RC connection, right?

Did you connect it to a free, unused cable from the CANBUS?

In my case, the green wire that fixed the issue was already connected between the CANBUS and the car’s OEM connector (where the head unit’s main connector plugs in). I had to splice it—connecting the AMP-CON wire to the CANBUS side, while leaving the wire from the car’s connector unconnected.

Not sure if Hiworld’s wiring diagram is different, but since these are Chinese units, they often share the same internals with just different branding.
