The Transits Ford has been churning out seem to be lower quality work. One of the repeating issues across them have been a failed stereo. Ford will charge upwards of $750 to fix it and they do so by replacing the stereo with a less crappy version.
This stereo I got from here works perfectly and was a fraction of the cost! Totally happy with the results and will be buying more for the rest of my fleet. We run a fleet of about 100 Transits so we see all the common issues with them.
