I have a AVIC F90BT running 3.0 I downloaded your version 4 Beta and have found the following:
1. The elevation sign is stuck at 0.2 feet.
2. The 3D view shows no street names at all. I can turn on Overview and get some side streets but not near what I had before. I can go to the 2D view and get no names either but if I touch the map any where and stop the "flow" while moving I get street names.
Nice work tho despite these minor issues. Any thoughts on my issues? I will definitely send a donation, please provide your paypal addy, I must have missed it.
