$300 is a ripoff. I just walked into the local Ford dealership asked if they could install the DMD for me.. I said since you guys have the right tools it shouldnt take you more then an hour to install.. and I would of done it myself but dont have the right stuff. He said ok.. $90 (hourly rate) and we will put it on. Worked for me.. droped it off in the AM before work.. got it that evening after work.
