I bought one in the last woot sale for my ford five hundred. I like the interface. But a week after I put it in the GPS won't load. Then I tried putting a CD in (I know, so 1996, what was I thinking?) and it won't accept a CD, like its being blocked by something as it gets toward the back. Any help on troubleshooting these, Metra, would be helpful. I've already had to shell out to have it installed, so things are getting expensive quickly!
