Just bought an extra license for my iid tool, {I have 2 rangey`s}
To get the unlock code, do I have to plug it in to the original registered car?
as I cannot access the tools menu when plugged into the new car

Check with GAP for the procedure .
Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember
Volvo V70 P2 2006 2.4 Petrol 170bhp Estate SE
MG Midget Mk1 1962

Previous: L322 Range Rover TDV8 3.6 2008; L322 Range Rover TD6 3.0 2002; P38A Range Rover V8 1999

Sorted!
All done, plugged tool into new car cleared faults (thankfully not many)
Set my speedo to km, everything is working fine.....at the moment.
Great piece of kit!
