Product Description
HomeLink Repeater Kit HomeLink is available in many brands of vehicles, and is identified by a single red LED and 3 buttons; some models may have a "house" image on the panel. On mirror applications, the house may be absent but there is still just one LED. Most older vehicles and select newer models will need a repeater to upgrade the vehicle to be compatible with the new Security+ 2.0 radio code. Gentex Corporation has a website to determine vehicle compatibility; go to
www.homelink.com and follow the steps to program a vehicle to see if you need the kit. Sample HomeLink in-vehicle system Sample HomeLink in-vehicle system Programming HomeLink-equipped Vehicles to Older LiftMaster Garage Door Openers & Gate Operators

www.homelink.com and follow the instructions.
Car2U Vehicles Select 2007–2013 GM & Ford vehicles may have Car2U remote systems manufactured by Lear Corporation, identified by three yellow LED lights, one above each button. The HomeLink repeater will not work with this system. A Car2U repeater purchased from Lear is required for all vehicles. Contact Lear at www.learcar2u.com or at (866) 572-2728.
