I did a search thru the forums, but I didn't seem to find anything about it.

I know that the TomTom devices usually handle your phone in two different ways:
a) as a modem to connect to the Internet
b) they act as bluetooth speakers (the tomtom devices).

I was then wondering: how difficult is to make the 770/N800 ACT as bluetooth speakers for a bluetooth enabled cellphone ?

Does the Navicore do it ?

This, along with the possibility of actually CALLING thru the cellphone, would be really great.
