ok, i talked to my mate who is the audi service manager and asked whether they did any retrofits of parking systems. they said they use a local car audio place that uses a german aftermarket oem/audi kit and installs them. full intergration with the audi rne. ill stop by and have a talk to them. i think they use kufatec
at this stage, im looking at all options and if it costs, then it costs.
