Hello;
Just picked up an AVH-P4300DVD for my 08 Honda Ridgeline. The issue I've run into is that the P4300 has just the one remote (blue/white) wire. My system has 2 amps - that alone would pretty much max out the ~300mv that the unit puts out on the Remote lead. I'll also need to send a signal to the antenna as it's amplified (crappy reception if you don't). Now we're talking 3 devices. I think the general rule of thumb is that 3 or more devices on the remote wire and you'll need a relay.
I'd also like to do the parking brake bypass as well. So if my thinking is straight I'm now
