Didn't quite work for me. When doing step 3 I got the 2nd message and then another about data being pulled to a location on the USB. I continued on following the steps though. The.lyc file was already in the license folder but I copied over it just to stay with the directions. When plugging back in the USB I didn't get a message but the infotanment system did go black and reboot and I removed the USB. The system was then at the main menu and I inserted the SD card but got no message and when I go to the navi I still get the 'Your Mazda is not equipped with a navigation system.'

Only other difference was that my SD card is formatted in exFAT due to being 64GB. I can try to reformat in FAT32 with a third party program if you think this was the issue. Also, are the files in the SD card supposed to be in root or in the BHP1 66 EZ1C folder?

GPS devices show the user the road direction by showing the maps of different places. As days go by, the roads and transportation systems change. So updating GPS maps regularly is necessary to get the full advantage of GPS devices. Many people customize the GPS maps in their own preferred ways.

Desnav GPS Navigation (Navteq) - Why Desnav? - FREE map updates - FREE application updates - Maps are installed locally on your device. To install (you can only install maps that have a serial number activated for that particular map).

Often it happens that when people buy a new GPS device, they need to transfer files from the older GPS device to the new device. This is because the new GPS device is not updated all the time. Serial port component for lazarus come out. If the two devices have different map formats, the files need to be converted.
