Just put in a Mods4Cars SmartTop for the S5. The actual model is listed as A5 Cab but it works for both and I can confirm it will work as it should on the 2013 model as well. The connections in the instructions are the same. Installation was straightforward and took about 15 minutes. The instructions were clear and concise. This is the second SmartTop I have installed, also did one on a Porsche Cabrio and both have been simple and painless self-installs.

Can now remotely open or close the cabrio top, also remote windows only, up or down if desired. Inside the cabin, engine on or off, I can pull and release to open the top. No need to hold the switch up or down. The best part for me is that I can set the car windows to go down while putting down the top instead of them going all the way up. I don't know why Audi does that but this module gives you the choice during cabrio top open/close. Nice to start top opening and windows down as I walk towards to the car to drive away.

 

So is this an additional remote you have to carry or does it somehow work with the factory key fob?

 

Factory key fob. 3 presses of unlock = car unlocks, cabrio top opens and windows go down. Nice while walking to the car in the parking lot. 3 presses of lock = cabrio top closes and windows go up, car locks. Hold down key fob lock = all windows close. Hold down key fob unlock = all windows open.

It all works with factory car equipment, nothing additional. Check out the mods4cars website, check the manual for whatever car you are interested in, there are a lot of configurable options you can program into the unit. I love this thing.

 

Very cool....Thanks for the info.
