Aftersales Radio Control
In Sweden it is quite popular to install an aftermarket stereo together with the Connect2
unit/harness. (Alpine stereo in the picture)
The connection schematic (CTSSA001.2) is this:
It works but there are some irritating limitations:
The Connect2 unit cuts the power to the stereo when the Ignition Key is turned to LOCK
( which happened every time one stop to drop someone off)
The Connect2 unit only puts power on the “Reverse” pin on Automatic Transmission cars
( not possible to automatically switch to reverse camera on MT cars)
