I have bought a tomtom sat nav and want to know if there is a fuse or point designed for supplying the power.
I am thinking a double cigarette lighter point tucked up under the dash, I do not want a satnav holder on display and it will be used in 2 cars so using the supplied 12v power cord would seem to make sense.
The second 12v socket could be used to power my phone.
also see seperate post re mobile phone bluetooth connection.
thanks guys

I took the power for both phone and Tomtom from the standard phone connector that is normally taped up behind the glove box.
You can also use that connector to feed phone audio through the main system and radio muting. There needs to be a transformer, for some reason referred to as a relay, to couple the audio signal. I think it's present in later cars, it certainly was in both mine.

thanks for your input, did you wire in the satnav and phone or did you put in an aftermarket 12v socket?
-
The phone I wired directly, for the satnav I fitted a socket so I could keep its original cable.
Both permanent and ignition switched supplies are available at that connector.
-
Can you let me know what bits you used or is it best get a auto sparks to do the job?
-
Soldering iron, heat shrink sleeving, power socket from Maplin and multimeter to trace supplies.
The pins in the standard connector are identified in the circuit diagrams, if my memory still works.
