Elvin:
Here is some additional information that might help you come to a better understanding.
There are four software components involved in any auto-routing Garmin GPSR. These are:
1) The system software that runs the GPSR itself.
2) MapSource.exe , which is an application that installs on your PC.
3) The cartographic product (in your case, City Navigator Europe) that contains detailed map data.
4) A basemap that is burned into your GPSR when it is manufactured.
There is no upgrade process of any kind for item 4), the basemap. No upgrade is needed, the basemap has remained unchanged for several years now. You will have either a European or North American basemap (referred to by Garmin as 'Atlantic' or 'Americas' basemap), depending on whether you bought your GPSR in Europe or America.
The system software that operates the GPSR is periodically updated by Garmin. These updates either fix problems that have been discovered, or add new functionality to the GPSR. The current system software for the SP III and the original BMW Navigator I (which was based on the SP III platform) is 2.50. Garmin's policy has always been to provide system software updates free of charge to the GPSR owners without limitation. If you need newer system software, visit this web page:
Garmin Software Updates
Garmin also offers free updates to the program 'MapSource.exe', which is used to load map segments onto your data chip, and also to create routes and waypoints on your PC and download / upload this information to and from your GPSR. The current version of MapSource.exe is 5.4 (as of today, March 4 2004) and if you would like an update for it, you can download it from the same URL as I gave in the paragraph above for the system software updates.
This leaves the issue of map data updates. These are not free. It might help you a bit if you understand that Garmin themselves do not collect any map data. They buy the map data from a variety of vendors - principally NavTech BV, which is the Netherlands based 800 pound gorilla of the electronic mapping business. Garmin then recompiles the NavTech data in a format that allows use in the Garmin GPSR's (as opposed to using it straight off the CD, which is what most in-car systems do), and Garmin then resells this data under their own brand names, such as "CityNavigator", "CitySelect", and "MetroGuide".
Historically, Garmin has released new versions of the mapping data about every 18 months. This process has been accelerating recently - if you track it from when the autorouting products first came out in 2000, you will see that it is headed more or less in the direction of having annual updates, although this is not a formal commitment. Garmin's policy, which is heavily influenced by NavTech, the copyright owner of the map data, is that they provide one free update (to the current shipping product) to anyone who purchases a new GPSR that comes with an old map data CD in it
after the official release date of a newer version of the same data. The most recent release of CityNavigator Europe was version 6, and this was officially released on December 1, 2003. If you go to this web page
Garmin Map Unlock Page, you can see the release dates of the current products.
I don't know if the policy for map updates is any different with the BMW Motorcycle Navigator (I or II), however, I presume (note carefully:
PRESUME) it is the same as it is with the normal StreetPilot products that the BMW products are based on.
What this means, then, is that if you bought (and subsequently unlocked) your SP III on or after December 1, 2003, you will probably be eligible for a free update to the current shipping product. If you bought and unlocked your SP III prior to December 1, 2003, you will have to pay for the update.
I have written to a contact of mine at Garmin and asked for confirmation that the upgrade path for maps for the BMW Navigators is the same as it is for the similar Garmin products. If the answer is any different than what I have posted (presumed) above, I will post the new info as soon as I get it.
