hi, i've successfully
install in my ECHD China 2din player in ford ranger.
just make sure your sd card path (SDMMC, MMC, StorageCard or Storage Card)
download the appropriate file according to your sd card address
in root of your sd card, put Garmin folder.
copy all files in the folder.
download maps.. there you go.
luckily my player can choose which navigation file (*.exe) if not must use shell to use WinCE interface
