Hi again Andy , I'm taking the aftermarket unit from my ford. BUT, after buying this voyager a couple of weeks backnow, I had to get the factory radio unlocked only to find out that there was no sound and an error whenever I inserted any sort of CD. So I'm assuming the factory unit is shot, I'm just preying it's not an amp issue instead! I'm going to try and fit it next weekend and I'll keep a photo/video log to keep you all updated and hopefully should it be successful it might help some others out there seeing as I've found tens of similar questions across this forum and other chrysler forums. Thanks again Andy for your reply. You helped hugely with my other issue, it was a jammed open thermostat in the end. I fitted a new in-line thermostat and it's working beautifully now
