2k for GPS, consider this...

I have the favtory nav in my M5 and it is so so. But I have a little crappy Garmin Etrex hooked into my laptop that I have loaded with both the garmin mapsource street maps and the usgs 7.5' topo maps from national geographic. This is a great system and since my laptop has such a big screen, it allows good details at a glance while I'm driving. Plus the topos are very detailed which is great for offroad use. I still want the factory nav for the OEM aspect, but for trail use I will stick with the old trusty laptop.
