I have tried installing NextGen on my 2 din unit.
Igo Primo runs perfectly buy NextGen is playing up.
It installs and allows you to set your preferences.
The problem is that after 2 or 3 reboots it resets to the configuration screen as if the program had just been installed.

The unit has an internal sd memory, external_sd for the GPS, and external_sd_2 for music.

Is there a sys line to fix this issue and where is the best place to install it?
