There is really no manual on how to perform an installation of a GPS on a MC as there are so many models to combine.
But, the basic principles are the same. You have the vehicle, the GPS, the cables and you need power to it.
This is the description of how I did the installation of a brand new Garmin Zümo 660 on my 2008 Vespa GTS 250 i.e. ABS.
I hope it will help someone out there who is a little afraid of accepting the task or simply don't know where to start.
Enjoy!
