Thanks for the quick reply.

When did you buy unit?

My first one was bought 2 weeks ago.
I wasn't playing with GPS untill a few days ago and noticed problem.
My 14 day return was up today and that is why I tried another unit.
I wonder if there are issues with satellite receivers on first batch of units manufactured.

Since second unit does same I may not keep N810.

It shouldn't take 10-15 minutes to aquire satellites.
My Garmin Nuvi does it in 1 minute.

Iam sure I have done eveything I need to on unit to enable its function.
