My radio will not turn on for the most part, sometimes lights up the buttons on the left side of the screen but black screen. If it does turn on it will freeze the screen (eventually get lines across the screen) or make whatever is playing stay stuck skipping through the speakers where I have to pull over and shut car off. This started after doing last update on radio. Have had radio for about 2 years. Need a fix or replacement asap please.
@Nelson Vega Please kindly send us the order number and go to Settings > About machine to send the current Build Number and MCU version.
In the meanwhile, please let us know how long and how frequent does the issue happen?
@Support Dasaita my radio has been completely going black or not turning on every day for the last 3 weeks. I cannot use it at all and it say mcu file not found so I can't send an mcu file. Order # SP-DA1200
@Support Dasaita I've replaced the 15 amp fuse in the unit and it still just turns on randomly for a few minutes and either the screen freezes with lines going through it or it goes dark.
@Support Dasaita still waiting for a response?
@Nelson Vega Sorry that we may have missed your message due to the heavy season. We found that you said the the head unit could be turned on randomly, could you go to Settings > About machine to send the current Build Number and MCU version?
