Basically what gps are u using. Are you getting a good signal. Reload streetdeck to see if that help. Streetdeck has it flaws but that ridiculous what u are going thru. the main problem i have with streetdeck is the multimon. Its just crazy how it jump to the second monitor for control. The whole point of streetdeck is for it to be a car mobile entertainment frontend. I can switch the front monitor to be the second monitor but that just crazy. its too complicated. I just wish they fix it where when u turn on multimon that the front still has control and dvd and other media will play in the second monitor.
