Actually it is an installation. when you boot with the SD card inserted Miopocket copies itself to the internal 2gb flash. some things go in the Windows directory for example. it adds registry settings Etc. but the AVIC software is also still there. thats the problem though, the AVIC software is still king. the only way i have been able to get to the MioPocket stuff was a bit of luck really. i boot once with the SD card in, remove SD card on reboot, wait for AVIC to boot, re-insert the SD card and most of the time the start menu will come up or sometimes MioPocket will take over completly.
