Wow... you're right. The back of it says U7140. Shows you how much I know...

The serial number is d0059cb and software version is v.9r01. Anyways, any suggestions? I also got an email from Garrett working there and I will respond to him later today.

Thanks for the clarification!

I'm kind of a newbie with all this stuff, so if this has already been covered or if I sound really dumb, I apologize in advance. 8)

I own a U7145 which I used on my 2005 Mustang GT. I have recently purchased another weekend car in a 2008 Shelby GT500. I know that the U7145 has been discontinued ...
