First i downloaded PC software, installed it on my PC and then started it.
then i installed software (from pocket navigator -> windows ce) and installed the data (map and language) on microSD
when i put the micro sd on the 2Din car DVD i started the navigator and select the free version it ask me to select the language after i select it the navigator exit and refuse to start again, i dont know what the problem,
question 1: how can i fix this problem.
question 2: the maps and language files (*.mca file) must be installed in data dir or in the root of microSD.
