cliffcoggin Posted May 9, 2016 Share Posted May 9, 2016 I use the cigarette lighter outlet for a satnav in my A3 Sportback and was surprised to find the outlet is live even when the ignition is off, leading to the possibility of draining the battery if I am not careful. Is this normal? Quote Link to comment Share on other sites More sharing options...
James Posted May 10, 2016 Share Posted May 10, 2016 I'm fairly sure that's how they come on the A3... Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 10, 2016 Author Share Posted May 10, 2016 Thanks James. I guess I shall have to poke around in the wiring to find a supply that is switched with the key. Quote Link to comment Share on other sites More sharing options...
James Posted May 11, 2016 Share Posted May 11, 2016 I always find using a fuse tap/piggyback is quite a neat way of doing it as you don't have to chop any wires etc Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 11, 2016 Author Share Posted May 11, 2016 I haven't seen those until now. I must investigate further. Quote Link to comment Share on other sites More sharing options...

cliffcoggin Posted May 18, 2016 Author Share Posted May 18, 2016 After a couple of false starts the sat nav is now permanently wired to a key switched circuit. Thanks for the tip James about piggy back fuse taps. An added benefit to the job is having less than a foot of wire on show above the dash, so it looks far tidier.

Glad you managed to sort it - the fuse taps are pretty useful for all sorts of things! Quote Link to comment Share on other sites More sharing options...
krolwioski Posted February 12, 2019 Share Posted February 12, 2019 Are you able to give more details how to do that? As i do have same issue. I have bought some amazon fuse taps, but it did not work for me. Maybe those needs to be special piggy back? EDIT: Looks like I have an answer already, as I have flipped fuse taps around, will test that later. Quote Link to comment Share on other sites More sharing options...
