Not sure where to post this so here I go. I'm stationed in Okinawa, Japan and I just bought a 01 Bb and I was looking to upgrade the head unit to something more with a aux input with Bluetooth. I just need advice with what to buy as far as brackets, wiring, and the unit itself. Keep in mind they have to be able to ship to an fpo ap address

 

I'd start with Crutchfield's website...they should show the HU options and also be able to provide any necessary brackets or wiring and I assume they can ship to an FPO but you'd need to confirm with them.
