I'm off to Italy on the Forza and have grasped the nettle and fitted a phone mount (I'm more of a paper map and post-it person. generally). My question is: to run a lead from the USB in the cubbyhole to the mount, is there a way of doing this without compromising the waterproofing? Or do I need to drill a hole somewhere? It's a quadlock, fitted to the righthand brake reservoir.
All advice gratefully received, including on using Waze/Google maps or another GPS app!
Tante grazie (as they say in Italy

)
