I paid $571.00 for the kit, but that included overnight shipping, I was in a hurry to get it installed on the weekend.
The kit included the module, the eject tray, bracket, various screw, wire ties, etc. The instructions were excellent. I had no problem with the install at all. The biggest problem was disconnecting the battery, always a pain removing the spare tire, and removing the oddment tray. Other than that, it was a breeze!
I have to say that both Randy and Calvin were great to deal with. Randy told me that if I ran into problems to give him a call or e-mail and he would help me out.
I did try to avoid installing the eject box because someone told me that I did not have to since I was using a bluetooth phone. Once I installed that everything worked great. Thanks to UCrewX5 for that information.

Definitely recommend them!
