Hi L&C that doesn’t seem right, my experience is that some dealers will say pretty much anything to try and get out of a potential hole !
Try Hamid at sat Nav system Chertsey, They sorted an incorrect head unit for me and coded it to the vehicle, along with voice activation. Dealer approved
my Missing DAB function on discover media, I insisted the dealer put it right, had to point out that selling a vehicle with an advertised spec that was missing is in fact mis- selling and illegal !
Many of these dealers sign up for the ombudsman scheme, do your reasearch on the dealer, and don’t let them fob you off, insisting you get exactly the correct spec you paid for ( they advertised / you Ordered)
PM me if you would like to some more info on how I dealt with my issue.
You do have the right to reject the vehicle, but I suspect you would rather have it sorted at their cost.
