Help With Tomtom Hard Wire To My Aygo

[autt86]

Getting a bit fed up with having the TomTom cable trailing all over the car to the cigarette lighter, so wouldn't mind getting it hardwired

http://www.buybits.com/product/sku_3110.aspx

just like to know what is the best place to wire the cable to? anyone could help?

I'd wire it up on the feed for the radio.

You've got ground, permanent and switched +12V feed there and

they're all fused with enough marging to feed an extra TomTom too...

You can choose if you want to use switched or permanent yourself.

sorry i dont understand what your on about!:D so the best place is to wire it to the radio + and ground the - to a bolt or somthing in the car?

[Jan van de Wouw]

The plugs for the radio have both a plus and a minus in them.

Actually TWO plusses: one that's allways "on" and one that

switches on the radio when you turn on the ingnition to ACC.

You can get a small extension harness (about 4 to 6") and plug

that in between the radio and the original cabling, then you can

use the wires of the extension harness to tap into. That way

you don't have to mess with the original wiring of the car.

Such a harness would look something like this:

Will be only a couple of £££ at Halfords or similar.

One plug is fully wired with green, grey, white and purple wires (and their striped couterparts),

the other one will have a black, yellow red and orange wire, maybe a blue one and/or several grey ones,

Black is ground, yellow and red are permanent and switched +12V, not 100% which is which.

Tap into black for ground and yellow or red depending if you want the TomTom to allways

keep power or be shut down when you turn off the car (if the software is set to do so)...

thx for the fast reply, as i need to wire the + to a 12v, which wire on the car is the best to wire the 12v?

seem to be much easy

the easiest way is to wire in a cig lighter socket behind the dash and use the original tom tom lead as this has the ability to drop the voltage to 5 volts. Wiring the unit directly to a 12 volt supply will cause the tom tom to fry, tom toms operate on 5 volt 2 amp supply

The unit linked in the first post already steps it down to 5V so that's no problem.

These are very tidy to connect to the wire without having to break it first.

thats great:) but do i still have to wire the + on the mini USB hard wire kit to a 12/24 Volt power supply in the vehicle?

[Jan van de Wouw]

I'm sorry, but I think I've explained quite clearly where to hook up the hardwire kit.

Maybe you can explain wat's not clear so I can try to simplify even more?

My TomTom One GB has just packed up. :(

I can no longer operate the on/off button.

It's been fantastic over the last 3+ years.

It will cost 70 pounds to repair and 20 pounds for a new screen holder

that I have lost so I have just bought a new cheapo RAC 1000 Sat Nav

from Halfords for 60 pounds.

I don't need anything fancy.
