Weird Bluetooth Issue...Phone doesn't see car...

[southsider]

So, I have a 2006 X5 with 31K and a Blackjack II...they were paried and everything was working fine...phonebook, voice commands, just fine.

Several weeks ago, my bluetooth just went out. My phone couldn't locate the car and the car wasn't asking to be paired (usually a red light on the telephone button would be lit if the car wasn't paired to my phone)...about a week later (the week before i was going to go show the dealer my car and lack of bluetooth), my battery died...i have no idea why, didn't leave anything on or anything...BMW came and jumped the car and once jumped, the bluetooth started working again just fine...didn't have to repair the phone or anything...

About a week ago, my bluetooth went out again! I have no idea why.

Any thoughts? Ideas? Just really confused by the whole thing.

Thanks in advance.
