I did some historical searches and it looked like navigator used to work on the 8703. However the mapquest website no longer lists the 8703. Only the 8320.
Will it work with the 8703 and which version should I install?
I am currently using the 8703e (OS 4.2.x) on the Sprint network, and Mapquest Navigator works perfectly for me. I use it with the GPS often, and it is pretty accurate. I'll try to find a link for the app. as soon as I can.
