I really like my TOMTOM Urban Rider,
mostly for the curvy road routing option.
I have mounted it to (using the supplied
ram mount parts and a ball/screw part) to the left mirror screwhole of my FJR1300.
I wanted to have a simple way to lock the navigation device to the bike. And it should look unobtrusive... not like the monster shark cages that exist in the market.
So I invented the RIMA-Lock. It basically blocks the release button with a metal bar from below. And I thought that maybe somebody else might want it too. I found a couple of different solutions in the internet that inspired me.
The lock is intended to frighten off the casual thief, so you can leave your bike to have an ice-cream or go to the gas station´s potty without having to worry that someone snatches your TOMTOM.
The small visible lock on the one hand is a
lock but also shows clearly that your TOMTOM is locked and thereby discourages
the casual thief. Therefore the lock should be visible when looking at the
TOMTOM from the side.
Do not hide the lock. Technically the base plate is symmetrical so the locking latch can be mounted to ether side.
The picture shows that the latch has to be mounted between
the baseplate and the TOMTOM mount.
To remove the latch you need small flat nose pliers in order to hold the small self fastening nutand a Torx T10 to wind the screw.
The device comes preassembled for left side use. The latch has to be removed when a right side use is needed. Or if you dont want to use the pen / penholder.
The other security issue that the RIMA-Lock set adresses is the RAM-Mount System´s regular is of course the thumb srew. Everbody can loosen this in seconds and take of the TOMTOM or charging connector. This is prevented in my solution with a well fitting Inbus screw and a selflocking nut. If you want to unmount this screw you need a small flat screwdriver to keep the nut from turning and a 5 mm Allen Key. This definetely prevents the quick unmounting of the device / RAM mount arm. At your first tour take the Screwdriver and Allen Key with you so aou can adjust the tightness of this screw.
Teh pen with the pen-holder and securityrubberband is used to be able to operate the TOMTOM without being forced to take of your motorbike gloves. Of course only when stopped.
Because of the realtively unsenitive touchsreen of the Urban RIder the key in of Street Names can be quite difficult and frustrating with your gloves on.
With the pen this is really precise an easy.
The RIMA-Lock is mounted between the plastic mount (active or passive)and the square metal plate of the RAM Mount system .
The four philips screws have to be taken off. Take of RAM Mount plate. Then mount he RIMA-Lock base plate with the elongated holes in between and put the philips screws in again. Before tigtening the srews put in your TOMTOM Rider in the holder. Then slide the baseplate and locking latch up against the bottom of the unlocking buttan/bar. Then tighten the four screws.
(I say tighten... not brutally rip out the brass nuts that are in the plastic... so I say not toooo tight)
A word of advise : the threads that are inside the active
docking mount are brittle...
when you look closely at the fit of the metal inserts into the plastic you see a fine gap
use crazy glue to put in the gap... that improves the rigidity significantly...
do not use locktite to fix screw that go in there... you
will pull out the thread insert
when you try to loosen the srews...

so if you wondered why I did not answer... try it again... it will work
You will get an e-mail answer with the confirmation of your order and the information about how to pay(paypal or money transfer etc. ).
Or you can order with this paypal Button...
there comes a dialog that ask you for your delivery adresse etc.
I do not know all the online order rules in Europe
but if you do no like what you get you can return it in the first 60 days and I refund you 30 EUR.
I will keep 5 EUR for the handling and stuff. I think that is fair. If in doubt just do not order it.
In Germany the legal rules apply: Widerrufsrecht and I assume something similar exists in other countries in Europe.
Latch, Baseplate Screw etc. are from stainless steel
and therefore quite corrosion resistent.
The penkolder is from brass and steel... that might rust eventually...
The lock is a simple chinese lock that is pretreated with WD40 and should get a little spray once in a while
to prevent rust and help smooth operation.
