All that needs to happen is someone with some time and motivation needs to read the MIO forums over at gpspassion and make a new skin for the nav portion of this unit. The boxes on most NAV devices and all devices based on iGo do NOT disappear. Also the iGO software is not capable of 2D heading up.... this is not an issue with the Pioneer unit its an issue with the NAV software it uses.
Basically it comes down to this.... If the boxes annoy you enough make a skin for the NAV. Also very improbable but still possible that with the release of AVIC FEEDS Pioneer may release alternate skins and map color schemes for the F Series. I have already made my own custom color scheme for my unit its ridiculously easy.
