AVIC D3 problem draining battery

[Kevfra]

Installed a D3 the other day, tested everything after intitial wiring - worked fine. Left town three days and came back to a dead battery (brand new battery too). I'm wondering...the stock Becker would always play just using the power button, which means there was juice available all the time and not connected to the ignition switch. Might be the AVIC, given a chance, would pull down the battery if juice is always available? I know several of you have installed one, so did you have to recircuit so the power is hot with key on only?

I don't think the issue is as I described. What's going on is the car won't start. Won't crank even a little, not even a click. But I get a nice panle of lights and things seem otherwise normal. Too much of a coincidence to suspect my ignition switch suddenly failed right when I changed the radio. Is there an immobilizer that kicks in if the Becker is removed?

I have the AVIC installed and haven't had this problem.

Did you wire the "always on" and "switched on" positive wires properly?

Kevfra,

Any updates??? I'm looking to install the Avic soon and wanted to see if that was the problem or something else..

[Kevfra]

Yes things are fine, and it had nothing to do with the AVIC. There was no battery drain. What happened was the installation triggured the security immobilizer. I had to reset it, which was a pain, but that's all. Everything is fine with the AVIC.

Now that being said, unless it is a matter of dollars, I'd buy the new generation and not the D3. The screen is much improved, and the GPS data disc doesn't have to live in the CD drive.

If dollars are primary then I'd say I'm very happy with the AVIC. Good sound, lots of functions (half of them silly and useless though), not very easy to use. But quite an upgrade to the car and looks great. I love the iPod features that allow you to bury your iPod for life and use the main screen for all controls.

Im thinking of getting an avic becouse you can custumize the background with the porsche logo! And getting true's kit! have you done that?
