Back of mirror has to show Ver 4. If it is Ver 3 it will not work with rolling codes. Most on Ebay are Ver 3. Amazon sells an adapter that plugs into ac outlet in garage that will convert Ver 3 to a rolling code.

Suggest connecting both to switch power. I did. Works grest. If you use constant power a thief voild break into your Maverick and open garage door. With switched power Homelink only works when vehicle on.
You probably have a Homelink Version 3 mirror. Need a Version 4 mirror to work with rolling codes. Look on back of mirror. It probably says HLV3. Need HLV4 to work. Amazon has a Liftmaster box that plugs into AC in your garage and converts your V3 signal to V4. About $39.
