Has anyone used an android tablet GPS app connected to their cell phone

I've got an old smaller size Samsung tablet that I think is the perfect size for a gps. Does anyone have any experience with using using a tablet as GPS?

Worst case I just use google maps on it and try to load gpx files using mymaps on google.

I've been using an android phone as my GPS for a while now. (I don't use a sim card in this phone, so it would be very similar to a tablet).

Generally, I'll use Google maps for any on-road travel, and have become a fan of Back Country Navigator for the off-road parts.

That's for the free, ad supported version. There is also a "Pro" version without ads. I use the Pro version, fwiw.

Rudy i use Osmand on andriod as my back up GPS. It can manage gpx tracks.

Thanks Guys, I'll give both these suggestions a try.
