 Content of the package

A lot of bagsOpening religiously all bags...

The difference in price between a TomTom GO may be explain by the requirement of using a GPS on a motorcycle. But what can explain the difference of price?

TomTom Rider

  • Has an aluminium case, waterproof, and a lot slicker than a TomTom GO
  • Is shipped with many goodies: textile bag for transport, bluetooth handsets receiver, 2 handsets (one for the cars or street, one for the helmet)
  • Has many fixation systems made of black aluminium...


The first time You'll start the TomTom Rider, You will have to answer a lot of questions: settings preferences, testing bluetooth wireless connections with Your celullar or the headset provided.

I was encountering problem when I first try to install the bluetooth handset, I decide to look at the firmware revision, what was installed was the 5.410, a quick jump at TomTom in the section download reveal that a version 5.420 was available since the end of november.

The update take the form of a "big and monolithic exe of 6Mb", wenn You start it, You only have to follow the instructions, It is recommended to do a backup first of all previous settings (user preferences) and to backup the existing TomTom SD cards, for this there is 2 entry in the main menu. It took approx. 10 minutes to backup 360Mb of it look like USB1.1 data tranfer rate...The connection to my Sony Ericsson K750i has worked like a charm, Contact database and messages has been synchronized without nay effort (Yes You can use your TomTom Rider as a free hand telephone!)

The installation has run flawlessy, there is really no dfficulty for a non informatician to act with the device, all menu are clear and readable. Personaly I dont not like the awful icons with their limited color scheme. Why Do I have to support then when so much icons are available under GPL? anyway the menu are crips and clear.

I look carefully at the filesystem backup and found in /TomTom-Cfg a file birthday.txt which maybe may contains when my device has been build: vr 14-10-2005 12:53

 Installing Radars overlay

Since TomTom 5.0 no additional 3rd party software are needed, POIs (Point of interests) like restaurants, petrol gas stations, golf... are supported by the TomTom kernel natively. POIs are simply a set of GPS coordinate organized in categories along with some metadata like telephone number, internet adress, contact name etc...

Managing POIsPOIs can be selectively activated on Maps...

POIs are displayed on a MAP using a technique of overlays.

  • Radars overlays are files with the extension OV2, along with some BMP representing how the overlay catgory look like.
  • Overlays has to be put in the same directory as the map it refer, for example map overlay has to be put in the /france directory.

For each category of overlay (a category is simply a way to sort all element semantically: fix radar at 100, mobile laser radar are 2 examples of street radar and can e place in 2 categories), You can set when to be warned, (Icon Warn when near POI) usualy by setting the distance in meter when to trigger a sound.

Select a POI categoryThen when to be warned...

The table below present You some values which can be taken as a basis, there are base on the distance you may need at 120km/h to adapt to a new speed....

Your speedRecommended Distance
20-50 km/h 200m
60-70 km/h250m
80-100 km/h 300m
110-130 km/h 350m
Mobile Radars300-500m (laser range at 400m)
Street signal100m

Then choose a sound, 15 are available,but You can store Your own (WAV format) and use them as well. In case of POI, a bref warning is recommended



Why? Because You may be not alerted if the GPS do not think You are on the same road as the radar, since the GPS technology and the radars database has an accuracy of +/- 20meters You may be catch by a radar

 TomTom is using Linux!

What is really interesting is that Tom Tom use heavily Open Source software and redistribute as state by the GPL the modified source code (More to read at )

  • Blowfish (The Blowfish Encryption Algorithm) -> Maybe for encrypting the ROM or some sensitive data like MAPs
  • ClipUtils (The Cohen-Sutherland line clipping algorithm)
  • CoRDiC (Coordinate Rotation Digital Computer)
  • MD5 (MD5 message-digest algorithm)
  • Ogg-Vorbis (Tremor-variable)-> Even If I have found no ogg vobis compatible file, wav seems to be supported through...
