|
|
I'm going to connect the TomTom supplied cable for the rider mount directly to the battery. The mains charger is rated at 5V,2A so I think a 1 Amp in-line fuse should suffice for the 12V bike cable. Presumably the voltage is dropped within the mount. Will a 1 Amp fuse suffice?
I notice there are four contacts on the mount - that's supply + and -, what are the other two for? |

If you tape over the 3rd one on the mount (2nd one on the RIDER) then you'll disable the 'Safety' menu, meaning you'll have full menu access all the time. _________________ Tim |

Thanks Tim,
I assume you mean 3rd from the left of the mount, which will correspond to 2nd from the left when viewing the rear of the Rider unit?
Taking pin 1 as being on the left of the mount (viewed from the riding position), as far as I can see, pin 1 is +5V, pin 2 not connected, pin 3 is earth and pin 4 is earth. That suggests it is the grounding of pin 3 which disables the full menu system.
Is the menu disabled whenever the rider is placed in the mount, or is it only disabled when moving? |

Having successfully wired up the rider on the bike (using 1 amp in-line fuse) a test ride established all functions working OK, all the time! No restricted menu when riding! So no need to use the tape-over-a-pin fix suggested!
Have I done something wrong, or what? |
