Hello!
So far I've been quite satisfied with my Garmin eMap (and my laptop with Autoroute for autorouting functions). The whole setup is not that practical for short routes, though... due to the settin-up time... for the inverter, laptop, GPS... but worth the time for long and "complicated" journeys...

But hey! Before ordering my empeg this was my way of listening to mp3's as well!!! ;-)

My setup picture is here:

I'm pretty curious about the use of the empeg for map storing and route calculations... I'll try and get some more informations about it...

Bye for now,

Alberto
