Switched 12v supply
 

Hi, I want to fit a TOM TOM sat nav to me xt660z and am looking for a switched 12v supply or volt free contact. Any ideas would be great. Cheers Ian

The best way to connect a sat nav on the Ten is by using the spare connector behind the panel under the dash. If you remove the panel you will see this small unused black 2-pin connector sitting under the tacho. It is wired into the sidelight circuit so will become live when the ignition is on (and also when the key is in the "P" position). It's also handy as the other pin is an earth so you don't need to faff about running ground wires. The sidelight circuit is fused at 10A, so when running a satnav a more appropriate 3.5A fuse would be a good idea, so as if the sat nav (or mounting cradle fails) it will blow that fuse and not the sidelight's.

The only snag is the male part of the connector is almost impossible to get hold of, so you will have to cut off the original connector and replace with something more common (as in the picture).

Can one also use that connector to supply a USB socket mounted somewhere close ?

Yes you can. Just make sure the USB socket has an inline fuse (usually a 2A mini blade is supplied pre-fitted).

Thanks a stack [emoji4]

Cheers guys great help, going to sort it today. Ian

Thanks from me too
 

Great stuff, knew the spare power socket was in there but a picture worth 1000 words etc. Feel a "fit a USB socket" project coming on....
