i have this unit Navigon 43xx max | 43xxT max and now is not connecting to USB data.
previously was full functional, but installed some GPS Menu and iGo Primo. After that, device was functional for few days, and all of a sudden wont turn on. tried some hard reset and now stuck on logo and wont connect to usb data.
USB port seems ok, and is charging by original charger and usb cable from computer.
is there a method to connect it to computer again ?
i would try to install navigon software back and use it with navigon maps as it was.
