I did the 3.5.1 install on Saturday and it went without a hitch. Replaced the V3 Nav SD card with the Version 4 and all worked just fine. The install took about 60 minutes to complete. I did have to enter in all of my favorites and Points of interest including my home in the Navigation. All of my SAT Preset stations were still ther but they were in a different order. My AM and FM presets did not change. My Wallpapers were also still there.
I did have to resync my iphone (still no texting support) but it works fine. My IPod seeking and use works just fine also.
No Problems with any features, everything seems to be working just fine. I did not have any issues before this upgrade FYI. I haven't realy noticed any big changes in anything with the upgrade.
One bummer on the upgrade: I lost all my Song ALERTS stored for SAT Radio....
