Hmm...that is weird. I will say the bluetooth update took much longer than I thought it would considering its small file size. I thought my unit froze up or something, but I kept waiting and it eventually finished.
I tried the bluetooth when I first got it for talking to people through the mic, but they said there was a lot of background noise so I stopped using it for that. I wonder if any of those kind of issues have been improved.
Hopefully someone can help you out with your issue.
