So if the 130 has u-connect there is a separate module. The 730 it is built in. What I did when I switched mine out is used the harness from the 130 to u-connect and modified it to work with the 730 so that the microphone for your hands free can work. That means you would need a second harness if you want to install the 130 back into another vehicle. I searched how to do it online. Let me see if I can find the thread. Also you will need a security code for the 730 if it came from a 2012 or newer. You have to get the code from the dealer. You have to give them the vin number from the vehicle the 730 came from to get it. It is a 4 digit code you enter into the radio when you first turn it on in the new vehicle.
