Navi 950 retrofit to Buick Encore
Hello everybody,

I installed the navi 950 in the Buick encore, reprogrammed the EEPROM with the Buick encore VIN and everything went great (head unit works fine). After leaving the car locked for a while and turning on the head unit again, there is no sound at all even turning signals or open door sounds dissapear.

Can anyone help to solve this problem?
Which pin on navi 950 turns on the factory amplifier?
And how to enable if not activated?
I found a temporary solution, pulled out pin37 (amplifier control) from connector A11 X2 and the sound came on.The question remains how to invert the amplifier control signal in navi950?(Now is when the head unit is on pin37 5v, when off 0v.)
The radio needs to be programmed properly so it knows it has UQA.
