Ford Kuga 2013 Titanium X
I believe Balders left his connected, so I don't think there's any problem in leaving them BUT what you've got to remember is, you don't have them. We only had them because they're necessary for Sync 2, there is literally no point. Don't over complicate it.I asked because you may only remove old GPSM module, but still could leave wires connected.
Interesting is. I will try to switch sync3 on sync1 GPS antenna, it will work or not...
