Does your Android HU have steering wheel remote inputs?
If yes, and if your only problem is that the signal is not compatible with the vehicle steering wheel remote, you will need a steering wheel control interface. See my post here for more info: Toyota Innova Owners & Discussions [continued 3]
If your Android HU does NOT have a steering wheel remote input, then tapos na usapan. There'll be no way to make it work. You can go "ghetto" mode and use a steering wheel learning IR remote such as this. This is assuming that the IR receiver is sensitive enough to pick up the IR signal from the steering wheel. IR typically works when the transmitter and receiver are within line-of-sight. But sometimes, if the transmitter is strong enough and/or the receiver is sensitive enough, you can bounce the IR beam and the receiver would still be able to pick it up.
