Last but not least you need to stuff all of this back into the overhead console.
The only place that has enough room to hold all of the wires and connectors is behind where the homelink slides into the overhead console. So poke all of the V1's connectors and excess wiring into that area before you put the homelink panel back in.
Then put the homelink panel back in place and plug the light fixture back in and put it back where you found it
The metal mount I used simple clamps around the back side of the mirror's post and hangs below it. Once tightened it will not move at all. Once you have this clamped on and adjusted you clip the V1 to it. Then plug the phone cable in you ran through the headliner.
That is a basic V1 install.
If you are using the Bluetooth adapter with it you will add it during the install simply by plugging its short included cable in the accessory socket of the V1's wiring harness you already have wired in at this point and then plugging the other end of the short cable into the Bluetooth dongle. The dongle plus the wiring connectors and such will fit in the overhead console just like the basic install.
