I recently got an appradio3 and had a 5 pin automotive relay kicking around. I was able to use the relay as the bypass without any additional components such as the TR7; this is done by utilizing the 5th pin(pin 87a) wired to the car's parking brake switch. In the past, you can wire 4 pins (30,87,86,85) on a relay 5pin relay or a 4pin N.O. (Normally Open) relay to simulate the parking brake being engaged. This no longer works with newer firmware as it requires the parking brake to be engaged, released and engaged again; hence the need for the 2 pulse bypass. Wiring: 30 to the deck

what about da210?

Start a call on the phone and turn up the volume on the phone. Not sure if this will apply but some phones have different volumes for different functions.

I'm in the same boat. The appradio 3 doesn't support USB audio play back does it?
