Satnav Install

Guys…I want to “plumb in” a transferable sat nav…so the power supply, an external antenna, an rds-tms reciever etc etc

any experiences or advice? I’m looking at the garmin 2720. what do you guys use?


I have a tomtom 300 that I transfer between a couple of cars and it is great. I have simply bought a couple of spare cigarette lighter chargers, chopped the cigarette lighter end off and wired them in to an ignition live, down behind the dash. Plus I have a windscreen sucker for each car. You can get all the stuff from Halfords.
