Hi Everyone.
I have just got a 2004 C180K and have decided to hardwire my tom tom to the power outlet in the ashtray. Does anyone know what colour the wires are likely to be, I need a negative and positive. Also, If i diconnect the battery, does this mean the stereo etc has to be re set by MB. Thanks

Best advice is to buy a cig lighter socket (Maplin sell them) and plug your tomtom power lead into that, then bury it all behind the dashboard. Wire the cig lighter socket to the back of your existing external cig lighter socket.

I doubt you'd be able to wire the tomtom straight to 12VDC without the little regulator they give you.

You may not need to disconnect the battery, just pull the relevant fuse.

Spot on Parrot - wire it in without the regulator and, to coin a phrase, you'll have an ex-tomtom !

Thanks for all the advice, I used to have it wired into the cig lighter in my last car (Volvo V70) ,so already have the adaptor and a built in fuse on the positive wire. Don't remember anything about regulators though. What do they look like and where would I fit one? thanks.

If you have a standard tomtom cig lighter lead the regulator is built in to the fat bit at the end (sorry to be so technical)
in other words if you can find some way of wiring that in permanently (eg by the suggestion of having another cig lighter socket out of sight) then you'll be fine.
cut the end off the lead and wire it directly to a power supply and the tom tom is history

Buy one of these:

And a bit of 12V wire for it at the same time. Plug your TomTom lead into that, then solder the wire to the back of your existing cigarette lighter socket. Secure the TomTom plug and the socket with some insulation tape.

The regulators in cig lighter plugs sometimes get hot, so leave it some space to breathe.

Then shove the lot behind the dash, tidy the cable up with a cable tie, wrap a piece of foam insulation around it (domestic pipe insulation would be fine) so it doesn't move around, and Robert's your uncle's brother.
