After a couple of hours worming my way up to Level-3 tech support at Motorola regarding Bose system not playing sound from Droid Razr via bluetooth in Altima after upgrade to Ice Cream Sandwich OS, they finally admitted this is a known issue. Another upgrade with a patch is coming next month. Meantime, beleive it or not, you can still get it to work:
1. connect to a call on the Razr
2. go to HOME - MENU - SYSTEM SETTINGS - BLUETOOTH
3. in the bluetooth menu there should be a gear icon next to "handsfree". click on the gear icon (while you keep your party on the line)
4. click on the little checkmark by phone audio, let it turn off, then turn it back on
5. wait a few seconds and then talk to your party.
I know. Huh?
