I only had one problem the first time I tried to program the Homelink. I had the Xfire out in the driveway. Since I have a "rolling code" garage door opener, I have to perform step 10 in the owner's manual as well. Apparently during that step, the car was simply too far away to "teach" the garage door opener the signal.

However, went out again last night at 1:03 AM and tried it while the Xfire was garaged. It took about four minutes.

To sum up, the instructions in the Owner's Manual worked great for me.

Bought the Xfire on Friday December 1 for the wife. We LOVE it.
