There was an unfortunate bug in version 4.20 which affects only those PNA devices which loose all of its internal memory and registry when they are turned off. Due to a typing error the registration key was not read from the SD card after boot-up.
Problem is now fixed, you should download the latest version of SeeYou Mobile which is 4.20.019. All versions from now on have this problem fixed.
Affected devices are AV8OR, MiniMap, some Navigon devices and a few other PNA devices which forget everything after power off. Oudie is not affected by this change.
We appologize for the inconvenience.
