Hello, I was running an older version of the OS system for my navigation system. My previous verison was V17. I upgraded to V29. I have a MKIII CD based navigation system. The upgrade worked, however, now I have a split screen view versus have a full screen view. How do I change to a full screen or have lost this functionality as part of upgrading my OS. I hope not...

If someone knows the answer please let me know..

Thanks
