hey there fishn, was it the dealer that made the error?
i took my truck to the dealer 3(!) times with xreas issues once they kept it for a week, they could never figure it out! my friend and i took it out in a big parking lot for 30 minutes and figured out what the problem was (he did really, but it was a 2 man job ;) )
10 days later the XREAS was removed and the ToyTec installed, problems solved!
