That's a bit of a trek for me, it'll be a B in Maidstone and Gillingham, I've only used them for the four year service so can't really comment on how good/bad they'll be with fiddly things like this. I'm not too fussed about the cost, I just need it sorted. The annoying thing was I booked it with a local firm on Monday to install a Pioneer SPH-EVO62DAB, checked with them on Friday that they've got everything they needed after several phone calls and pictures being sent, I even offered to bring the car in ahead of time before so they could properly look at it, but that apparently wasn't necessary. Of course an hour after dropping it off on Monday I got a call..."errr...sorry we can't get the facia to fit, so we can't install it" meaning I'm back to square one.
I have got a couple of irons in the fire with replacement units on-line, so I'll probably use the above quick fix by disconnecting the sat nav and get a decent auto sparky to fit the recon unit.
