so according to what I read, the n810 isn't my solution
I'm considering either :

- buy a garmin gps (with proprietary maps... that bothers me)
- buy a data logger bluetooth gps

for the second solution I've some question... is it possible to continue the logging while accessing the gps by bluetooth? for example if I put the gps on, activate the logging. I now want to see where I'm on the n800, if I connect to the gps with bluetooth, will it stop the loging?
thanks
