i did try the 3D, its just too slow, because everything is calculated in 3D so it takes more time to process the map, personally i dont care if any building is animated in 3D or not, the whole point of GPS is to give good accurate and fast information while behind the wheel. For me I just cannot get used to 3D view even with tilted to like 2D view. If I knew how to change it, for sure its very simple but since there is no such a thing like a support from either company, i can only hope they will fix it, but i think they will not, and they will only release some unimportant fixes.
I have been an AVIC F700B user now since last July, almost 8 months. I too was annoyed about 2-D mode not having the ability to track heading up. I was really hoping for a fix when each update came. They didn't. I had tried 3-D mode a few times, tried to like it and a few things like the Big Red arrow and all of the excess clutter and what not made me not like it. But then i did a lot of reading on this forum, asked some questions, read a bunch of threads. I resized my 3-D arrow, cleaned up some clutter, did the software bypass, got rid of the keybeeps and so on... I now love 3-D mode and can not even go back to 2-D mode. It works very well now and looks really good. I would still like to see that option added in the next update, but for now, my F700BT works very well. I may even upgrade to an F-90BT pending the release of a newer model in June. For those so annoyed, be patient, Give 3-D mode a shot and see what happens in a few months with a another update.
