I just started using the Topomaps app on my IPad 2. I have the dual 150A bluetooth GPS receiver on the dash and the IPad mounted in a Ram suction cup on my wins shield.
Thus far the App does what it says, I have a moving display of my position on USGS quads. The maps are not up to date, but I've actually been able to use that to find old roads that are closed but still passable. Not many frills on the App, but if all you want is an easy to see map it works better than having 100+ large paper maps to deal with.
The Dual GPS status App is really useful. It shows the battery life remaining on the receiver, satellite signal strength and other useful information in a really slick look.
I was worried about the mount vibrating but so far it works really well, but I have yet to do anything crazy with the IPad mounted.
