Can anyone tell me what this does, I think it may be a splitter for when the music is on and the vhf recives at the same time, so it mutes the music so you can here the vhf at the wheel. But ime not sure, anybody else know?
I found this on the old website for i-sotec.com - on Internet Archive:

Auxgate® Easy
Affordable all-automatic navi-integration
Auxgate® Easy is the best way to connect a portable navigation system to the car radio. It is only 80x76x27mm and fits behind or underneath nearly every dashboard. Equipped with a phone jack for navigation input and a volume controll for the navigation input level, it is very easy to connect and to use.
The well known SCOM technology automatically mutes the car radio if a signal from the navigation is detected. The navigation output will be heard through the front speakers only. You can decide by jumper switches, wether the rear speakers are muted completly or partially.
Plug and Go: Auxgate® Easy can be connected to any car radio with standard ISO sockets with just one click via the in-series DIN/ISO-adapter. For more than 500 factory radio types with non-standard connections, i-sotec offers adapters.

Thanks for that nuthatch, I had googled for isotech, and couldn't find anything on out of date stuff. I now know what the small dial control does.
Glad that helped!
