Which GPS is best for Mexico?

I do have the GPS with Microsoft and it works pretty good. Briandsue thanks, I will check your web site to download the POI. Just one thing I learned is to disactivate "provide navigation" cause this function keeps rerouting and goes on and off many times, probably because I am taking a "wrong route" wrong route" on and on and on, shut up, I know!

I like the idea of a lap top in the dashboard!
