Thats a good way to save time. For the first 7 months I had my JB4 I did all updates and map changes via laptop and data cable. Its not as convenient but changes aren't made that often anyway.Weird how you still have to buy the app after buying the BT kit!
Might just go the cable route cause I probably won't run past Map1.
I guess I could...but I won't I did not buy this car for fuel efficiency. I heard that while driving normally...it's actually more efficient.
