It feels like home. The HomeLink® system is integrated into the overhead controls of your vehicle and eliminates the need for other garage door openers. Based on a radio frequency transceiver, HomeLink® works with over 98% of home garage door openers. Three buttons means the driver can also program other garage doors, gates, and even lights in your home using optional accessories. Meshing the driving experience with the comforts of home is what HomeLink® and Audi are all about.
