Hi, I'm wiring up my Tomtom rider 450 to a switched live on my bike. I've found a 4-pin accessory plug (not connected to any other socket) under the seat but the voltage on the switched live varies from 12.08v with the ignition on to 13.8v with the engine running. The question is will this voltage be too high as an input into my Tomtom dock?
