Hello, I recently bought an 05 ram srt10 qc with the RB4 Navigation system. When i test drove the car - the stereo screen came up, "Battery Charge too low, start car or system will shut down in 3 minutes". Although, the car was running when it gave me this error. The dealer told me not to worry about it and that after i drove the car a while it would go away. No such luck, its been 100 miles and the unit keeps shutting down every 3 minutes. Checked the battery and electrical system, checked the radio fuse, and checked the harnesses for power and everything seems functional. Please, I need some help. Dealer not willing to help.
