[QUOTE="Simon Dinsdale, post: 120498, member: 58"] Be careful as not all GPS run direct from 12V. I don't know about TomTom's but my Garmin which is a motorcycle version came with a little black box in the lead which is a 12V to 5V converter as the Garmin unit has a micro USB connection in the back and USB is 5V. I know somebody (not myself) who connected a Garmin direct to their bike and not through a voltage convertor and that GPS no longer works. If you are using a car GPS and putting it in a waterproof case then your lead will have the voltage reduction electronics inside the cigarette plug. I wanted to be able to swap my GPS from bike to bike and so needed more than the single convertor that came with the unit so I used one of these voltage convertors mounted permanently inside the headlight and then put a waterproof plug tucked between the fuel tank & UFM so I can easily connect the GPS & its cradle to each bikey bike.
