Had mine in for about 3 days now and so far I love the thing. Only complaint I can find with it is that it won't maintain my XM presets (although it keeps the FM/AM/Navi ones) but I am guessing that is an issue I will have to deal with at some point but right now I just listen to about 3 XM stations so they are easy to just punch in. RTFM is definetly in the works for this weekend.
Bluetooth - Synched with my sch-i760 and pulled my contacts over with no issues at all. Has never dropped a call (and I spend a LOT of time on the road and on the phone)
IPOD - Couldn't tell you I don't own
