interesting... I have been stalling on doing the update as well. Keep thinking I will call, but I know that I am the only one with the MFT from the dealership I bought mine from and only a few have been sold from the other... I wish I could wait for them to try on other cars, but I think I don't have that option. But like you - I haven't had any major issues. I do lock mine too even in the garage because of the night light, but other than that - all is good.
