"For this review I tested ROUTE 66 Mobile 8 Europe.  The installation program on DVD installs the navigation application and all maps to a memory card. Since you cannot select which maps you want or don’t want to install, the Europe edition needs at least a 2GB memory card.
The first thing the installation program does is format the memory card. It even does that when there’s enough space left on the card for the ROUTE 66 application and the maps. No problem for my brand new 2GB microSD, but a bit inconvenient (to say the least) if you want to install the application on a memory card that already has lots of information on it. After the format, the installation program transfers the applications and the maps to the memory card. At least that’s what it’s supposed to do, but instead formatting made the card unusable and the installation was unable to continue. According to the people at Route66, this problem has been fixed in the next release. [Hmm..... not a good start. And the DVDs are mass-produced, so it'll take a while to get the fixed version into the market - Ed]
Luckily, the DVD also contains a folder with the name \MemoryImage. By simply copying this folder into the root of the SD card, the ROUTE 66 application is installed automatically the next time you insert the SD card in your phone." Read more here:
