Installation 2015-1 map database from USB:
First of all, you need daemon tools or any other similar program for mounting iso img files.
1.Mount the first iso file which contains firmware N42c. Copy folder HEADUNIT and HBUPDATE.DEF to an empty usb stick (fat32). Start the car and insert usb. System will detect update and you just confirm the update. Car must run all the way till the end of the update process!
2.Now mount the second iso img which contains map database from the first DVD and copy folder pkdb and config.nfm to an empty USB stick (fat32 formatted)
3.Insert usb in your system and system will detect map update. Confirm and wait…after some time the system will ask for DVD2. Now go to your pc, format usb stick and mound DVD 3 and copy folder pkdb and config.nfm to an empty USB stick. Now go to your car and insert USB and the update will continue till the end.
It's possible that at the end of update (11/13) you will receive an error message (error 0x26)
This error appear sometimes but it's nothing serious so don't worry, just press Ok to valide the message and the NG4 system will be rebooted. After the system reboot the update process will resume and finish the update.
Option #2 - If you want to update the entire map database From 1 USB stick, than you'll need 16 GB USB stick and do the following:
