Thanks for the replies so far, Kevin no it does not have original radio, and also I seem to remember there is no buzzer if you open the door with key still in, however I am sure the display above radio goes out when key is removed, will be the first thing I check. Greg, I tried to re-sync with vaux-com but I kept getting error message saying procedure failed refer to handbook. I assumed this was because no scantool is needed to do this, the procedure is in the handbook.

Wont see the van for a few days as off to Oulton Park in the morning, will call owner on Monday to re-book
