ohhh I saw the "660", but I didn't read the simple word "ZUMO" before the 660
About the A2DP adapter, I totally agree and I saw a few very cheap ones that I'll use the P2 headphone jack and that's it.
Thanks for the tip and correcting me about the zumo.

On the other hand, I've been searching the entire forum with no success yet... have ppl found a way to hack/change Garmin's password to 0000?
