I’m having trouble making all of the speakers work correctly in my f-150, and I have a large suspicion it’s the stereo, and I want to replace it for a new one regardless of the speakers not working. How do I know what stereos I can buy that will work woth the sync in the truck. I have the basic sync with no large screen or anything. I would like a touch screen, I just don’t know how to buy one that won’t require all kinds of adapters to stay working with the sync.
