Hi bbf2530
So guess what, once you install it in your car, and it does it's update, it will not let you re-install it again, I went to the Sync site it says I am at NA18, however the radio screen still shows NA17. SO I am not sure which is right, but I am no longer able to update the software and that is that.
SO I will see what happens over the next few days, will be taking it in for service in about 3 weeks, will get dealership to confirm the actual software status.
thank you for all your help,
regards
Fred
