I actually installed my Sirius Starmate Replay this past Friday. I didn't want anybody ripping apart my truck so I just did it myself. Since I don't eat or drink in my truck, I used the suction cup mount and stuck it in the driver side cupholder. I then extended the arm on the cupholder to give it even more support. I have been driving around a lot and my 'custom' mount is not budging an inch! Here is the thread I posted on it a few days ago:
