HELP NEEDED..CAR AUDIO GPS,NAVIGATION
I just bought a new car radio with GPS Navigation. The software "NPLUS" came on a micro sd card already inserted into the radio. I want to change to a different GPS Navigation program. I have seen online that some people are putting on free maps for navigation onto SD cards. QUESTION.....Can I put on any free Navigation software with maps on to my sd card and replace the original software and it would usable?
