Navigon version compatible with Mio Spirit 685 - no SD card

Can anyone recommend a working version of Navigon that is compatible with Mio Spirit 685 device with Flash disk only (no SD card). Runs win ce6, 480 x 272.

I have tried almost all versions from Navigon v7.xx to 8.xx but none of them work. The problem may be is related to absence of storage card on the device and most of the downloads relate to devices that have a storage card.

Within the 7.xx and 8.xx versions that I've downloaded, I did a search for all config, ini files and replaced "\SD Card\" with "\My Flash Disk\" but I still get the error: MN8 performed an illegal operation and needs to close.

Any help would be appreciated.

I have a similar unit. Only one working really well is 7.4.3! I've tried a lt of version 8's but none will work. I'd try 7.4.3.
Hope this helps.

I have the same unit Spirit 685 and I used visual GPS v115.01 with Navigon 775 version 447 and that works fine, you can find this on this board
