I bought an 09 nav to put in an 08 superduty from lothar 155 on ebay, garanteed to be plug and play, but it isnt and wont return my emails or phone calls, so beware. I have spent a bunch of time to figure out that it is the wiring harness from the radio to the amp, it isnt wired correctly and makes my dash lights not work on the left side of the dash. It isnt a ford part, it is a custom made harness( there is another guy on ebay selling jsut the amp and wiring and it has the same harness, part number and all). Im guessing Im gonna have to buy a harness from ford for a superduty, is that what everyone else has used? I jsut wanted to let people know not to buy from this guy on ebay, he doesnt stand behind his product and I piad a premium for this thing becuase of his gaurantee of being plug and play.
