I have upgraded the RadioNav unit in my 2010 Brera 1750 to a Pioneer Apple Car play. I didn't realise that the column stalk menu for clock setting, lock settings etc didn't work if you have RadioNav - it is all done through the head unit. After replacing battery my clock and date settings are wrong and I cannot reset them. I also cannot alter other settings. The odometer is also blinking (a common issue I believe) and with the blinking clock its a little annoying. The new head unit is vastly superior to the RadioNav so I really don't want to swap back until I sell the car. Its been into a leading Alfa Independent Specialist who connected it up to the computer but they say they cannot alter the clock settings this way and they can't get the canbus (is that right) to recognise the unit so can't stop the odometer blinking. Guess I can live with it if I have to as there is a clock on the head unit, but it would be nice to find a fix. Any ideas?
