To get the HomeLink system in the Crossfire to work with the newer garage door openers of today, you will need a HomeLink Compatibility Bridge in the garage. This allows the Crossfire HomeLink to communicate with the Bridge & the Bridge then sends the signal to the garage door opener. Here's a link to a website that provides this info: CLICK.

As I've posted in other threads about this aggravating issue, my new garage door opener came with software available via a downloaded app on my cell phone. So using my cell phone, I can open the garage door when in my Crossfire. In all my other vehicles, which don't have a 3-button HomeLink installed, I did purchase new door transmitters & replaced the older versions that we were using. I could have bought a HomeLink Compatibility Bridge, & then could have used all my old transmitters along with the Crossfire system. Just didn't do that.

If the wife was more comfortable using the cell phone, I could have installed the app on her phone, authorized her as a user on the garage door account, & just got rid of all the old transmitters.

Oh, and we did have an external keypad installed outside of the garage door so when we are working in & around the house outside w/o our cell phones, we can just enter a 4-digit code & the door will open. Pays to have a backup!
