Does anybody know if within the Enginnering menu there are any settings for the Nav SD card to enable the importing Data when sd card is slotted in the Ntg4.5 . for Nav PersonalPOI . This worked the first time i installed the sd card and the POI all worked well, I removed the sd card to install some music from another sd card to the music register, now the card with the POI on will not reinstall on comand !!!
