Just out of curiosity what would cause a modern HU to lose time? Battery and alternator are fine. Wiring behind the HU is fine. Over a month it will lose like 3 minutes. Over 2 months it loses almost 9 minutes and stops losing time.
I know back in the day they used to basically have a CMOS battery in them that would keep time.
Any ideas?
