Evening all,
Thought I'd share another retrofit that is currently in progress that I'm working on in parallel to my Side Assist retrofit. This one is for HomeLink support.
For those that dont know, Homelink supports the ability to primarily open and close your electric garage from buttons within your car. Many variants of Audi's have this as a factory order option but bizarrely for UK folk its not even an option on the Q7 4M but that doesn't mean it can't be fitted!
I've managed to get all the parts, primarily from a well know auction site in Germany and the first task was to fit the homelink buttons into the overhead roof console. I ended up buying a whole second overhead roof console and while I could have done a straight swap with my one, the one I bought had a few marks on it around the reading lights, so in the end I just swapped the homelink buttons and trim over to my one which is in better condition but it first involved me taking the one I bought completely apart which was interesting! (see below)
The second part of homelink is the main control module (and aerial) that is stored in the rear bumper. I'm not fitting it there because I can't be bothered to remove the rear bumper so instead just going to install it behind the luggage trim in the boot. The aerial for it has been run up the side trim of the car all the way to the front under the dash.
I haven't installed the main control module yet as I need some connector wires that I forgot to order from my dealer so just waiting for them to arrive but the other bits are done. I've attached a few pics of the install of the switches in the overhead console.
In addition, homelink can be used to control security cameras or devices that support the Z-Wave protocol like front doors locks, lights, heaters etc so one could use buttons 2 and 3 to say unlock the front door as you park on the driveway if your hands are full of shopping...

Will post a new update once the control unit is in and I've sorted the necessary coding.
