Hello do you have any solution on my problem while playing MP3 or FM Radio on my Head Unit. Igo primo map view is stops responding or hangs while my car is not motion and or sometimes when i'm playing MP3 and switched to another song the software map view stops responding. I tried all versions of Igo but no luck. My temporary solution is to touch the screen to make it working again. Any solutions on the sys.txt file to solve the problem?
