fitting a sat nav

I would like to fit a sat nave on my t80 but I don't think it will work due to the bike being 6 volt
will it work before I buy one and most important has anyone got one to work off of the t80s battery

Unless you find a 6V sat nav unit (never heard of any) then, no you won't be able to.

The only other option is to convert the lighting circuit to 12V like I have done on mine. A bit of tinkering but not difficult to do.

Lighting and ignition circuits on the T80 are seperate so you can leave the ignition on 6V and convert the lighting circuit to 12V and that opens a whole new world for you.

You should be able to run a sat nav on 6 volts read this thread http://forum.arielownersmcc.co.uk/viewtopic.php?t=2140
a guy on there did it. Townmate has negative earth so it should not be a problem, unlike the Arial owner with positive earth.

I have just come across this solution....

£12.49 seems good value.
I am tempted however by the idea of upgrading to a 12v coil and enjoying better lights.

Trust me andrewp, converting to 12V is a far better solution for the Townmate, long term you will be better off and if you want to go the extra step, 12V LED globes are readily available.
