I just got my X50 back from Escort after it started saying "service required", in my note I asked them to upgrade the software. (It was Rev. 6.1)
I checked what Rev mine is, and surprisingly it is Rev. 6.2!
I've never heard of anyone having this Rev. (Just 6.1 and 6.3), so I'm just wondering if anyone else has a X50 Rev. 6.2??
