Completed the install today, Everything turned out well. The phsical cutout for the unit IS NOT under the fabric. However,the square shape of the Homelink transmitter is somewhat visible on the plastic shell. I dremeled the area out and low and behold, underneath on the inside of the back plastic panel were the mounting squares and securing tit for the Homelink module. I ran the wiring through the visor and tied into the vanity light. The removal of the vanity light went ok, went on everyone elses R&R info. It has 8 small **** that press into the plastic frame underneath the fabric. The only problem, they would not click back in. I ended up flairing each tip slightly with a soldering gun which took up the slack and the vanity light clicked back into place.
