If you have a V6 registration you can upgrade it free to V7, just email me your V6 registration details (paul@efilive.com) and I'll send you back a V7 registration.

Look on the side of the AT1 unit and you will either see a silver sticker with a serial number on it or you won't. If the sticker exists then it is a V2, if there is no sticker then it is a V1 (V1's do not have serial numbers).
If you think the sticker may have been removed, then you'd need to hook it up to EFILive (and a vehicle to supply power), and attempt to connect to it. EFILive will show whether it is a V1 or a V2.
First image: select the AutoTap V1 cable type.
Second image: select to connect to FlashScan only - which simply means only make a connection to the interface cable (AutoTap or FlashScan) and not to the vehicle.
Third image: display the [F6 Console] tab page and view the details that are displayed by EFILive.
