these codes are for alpine electronics and they Do not give us this info. you would have to call them to see if they will give this info. But I will tell you the navi unit will have to be sent in for repair this is the issue here and a pretty common error we see at my dealer
last I heard alpine charges around 250.00 to service this navi unit.
