First of all, I was NOT chastising you. I only "yelled" at you because I didn't want you to inadvertently do something wrong. I'm not sure if the Mio 310x can use a 4 GB SDHC. Can you link me to its specs? BTW, there are ways to get around a memory deficiency. First is NOT to use dem files. There are others. What about the .dll files for 4.2? Do you want them?
Mio 310x CAN use 4 GB SD card but not SDHC. Non SDHC can be found but not too readily. You'd be better off if you can find such a card rather than using the internal.
We can always go this route:
To minimize: 1. Delete the TTS_LOQ folder 2. There are 5.dlls. You're gonna delete 4 of them but not gpstmc.dll 3. Delete all the TTS voices from content\voice leaving only the non-TTS voices 4. Include your content to the appropriate content folders 5. Delete all dem and building files from your content 5. Reduce the area or delete the speedcam files 6. Reduce the map and poi area.
