Hi all, I have a 2015 Maserati Ghibli that came with CTP16 and has the can't unlock maps error. I've spent hours trawling the internet trying to fix/update the maps but am getting nowhere. Any help is greatly appreciated. Here is what I have done so far.
Inserted USB in car to download map status using update maps option
Inserted USB in PC with Garmin Express installed - it finds CTP16 from USB but when updating I get cannot connect to server error
Downgraded car to CTP13 using CTP13 4.08.rar - success!
Inserted USB in car to download map status using update maps option
Inserted USB in PC with Garmin Express installed - it finds CTP16 from USB but says system is up to date
Downloaded torrent of City Navigator Europe NT 2024.10
Installed BaseCamp - maps are working OK on PC
Created USB image with following directory structure
Garmin\gmap3d.img
Garmin\gmapsupp.img
Garmin\ASR\all files from torrent download directory
Garmin\JCV\D8957030A.jcv
Garmin\JCV\D8958030A.jcv
Garmin\SID\all files from torrent download directory
Inserted USB in car and navigated to update maps option - nothing happens, it just writes another status file
After inserting USB into PC BaseCamp now says my device has CN Europe NT24.10 maps but I still get can't unlock maps on the dash in the car
Any ideas what I am doing wrong? The unit is downgraded to CTP13 and I have working maps on BaseCamp so I think I have all the tools to finish the job. It's just a question of how to build the USB image correcty.
