Thread: Nuvi 6x0 Software Versions Summary

If I'm not mistaken, the bluetooth firmware is different/apart from the main firmware.
I remember when updating the 660 firmware, I used to go to the extras on which I could update the bluetooth firmware and download other things. That was before Garmin Express, it was Garmin Updater (I think).

Have you ever tried checking to update your bluetooth firmware or reinstalling it using Garmin software?

I've just googled a little and found out that it's not only your issue.
The bluetooth problem usually manifests itself as such that bluetooth becomes disabled on the nuvi, and enabling it causes the GPS to lock up or freeze. Holding down the power button will reset it, but bluetooth is still disabled and re-enabling just causes it to freeze again.

You need to download and install the bluetooth fix.
