Another word of advice on Alpine HUs.
The 9880R and many others I believe usually don't turn off the iPod when you turn the engine off, unless you change the source, press pause or manually turn the iPod off yourself. That would mean your iPod will continue to play when you leave the car, resulting in a dead battery the next time you're there.
Now for me that's not such a big problem because I have 2 iPods, one for the car and one I personally use. However for those of you who only have the one for everything, Alpine will send you out a cable that connects between the HU and the iPod lead itself that's eliminates this problem.
I emailed them 2 days ago and got a speedy response, told them I bought it under a year ago and the guy asked for my address and sent it out, got it today
