Please help me to identify the best one 12v constant accessory wire in order to connect Satellite radio and GPS. Please advise which one is the good one to tap (is this ignition one?). If you have pics I would really appreciate it.

Thank you!

 

I don't think you really want a constant 12V+ line as the device will stay on all the time until you either shut it off or unplug. Instead, I'd suggest tapping the cigarette lighter plug. The center is the 12V+ and the outside is the -. I did this for my V1 install and it turns on/off w/ the ignition.

 

The cigarette lighter is probably easier to access, but you could also use the blue/yellow wire from the harness that connects to the back of the head unit.

 

Thank you very much for the reply. Could you please let me know what did you use to tap it? Is this quick splice connector or something else. Thanks again!

 

I usually use a utility knife to carefully remove the plastic from around the wire. Also, if you're in a pinch, you can use a lighter to burn away the plastic.

 

Though I'm not a big fan of them, yes I used just a splice tap connector:

 

I got it thank you!!!
