lukekbrown Posted September 28, 2011 Share Posted September 28, 2011 I'm going to retro fit a tomtom satnav in my cubby hole and want to hardwire it to the rear of the cigarette lighter or even get power from the bose head unit, so all the wiring is concealed inside the dash. Does anyone have a guide of how to do this? I know a few people have carried out the operation, so a bit of guidance would be great Thanks Quote Link to comment Share on other sites More sharing options...
scubapics Posted September 28, 2011 Share Posted September 28, 2011 I don't have a guide but what I do is buy some cable and a cirgarette lighter socket from maplins. Then wire this in behind the facias/dash into an existing socket. Then the tomtom can plug straight into that. If you buy a different tomtom in the future or need to take it out when selling, it's easy to just unplug/fit new charging adapter. Couple of cable ties to hold it all in place and voila. Done. No need to hack your existing tomtom charger and it all remains fuse protected by the tomtom fuse. PS, I think the front cigarette socket can be pushed out so you can get at the wires to splice in your extra socket. Jim Quote Link to comment Share on other sites More sharing options...
lukekbrown Posted September 28, 2011 Author Share Posted September 28, 2011 Thanks Jim. That sounds a great idea. Is it possible for you to advise what cable and socket I need? Maybe forward a link? Also How do I splice into the front 12v socket? Thanks Quote Link to comment Share on other sites More sharing options...
scubapics Posted September 28, 2011 Share Posted September 28, 2011 Splicing. Two options. The socket in the fascia has two wires running to it. You need to attach two new wires to these and then to the new socket. Make sure you get the polarity correct! If you have any doubt about this then get someone who knows what they are doing to do it for you. 1. Cut the existing cable in two, strip, tin and solder then heatshrink to insulate each cable. or 2. One of those blue crimpy cable joining thingys from Halfords. (sorry, don't know what they are called.). I always solder my connections 1 but if you can't solder then option 2. For socket (15amp): http://www.maplin.co.uk/car-accessory-socket-1055 x 1 For cable (15amp): http://www.maplin.co.uk/twin-power-cable-20666?ordercode=XS72P length to suit. For crimps: http://www.maplin.co.uk/snap-lock-automotive-cable-connectors-1073 x 2 The crimps are only 3amp rated. Do you know how much current the tomtom charger takes? If more then these are not suitable. Jim Quote Link to comment Share on other sites More sharing options...

coldel Posted September 28, 2011 Share Posted September 28, 2011 If you do could you put together a photo guide? Sure it would be pretty popular... Quote Link to comment Share on other sites More sharing options...
