Hi,
I have a MK6 Golf GTD and it came with an RCD310 radio. I decided to upgrade and buy a RNS510 satnav unit. On installing the satnav unit all the functions work correctly, bluetooth, steering wheel controls, sat nav, radio, phone etc. however when the engine is switched off and the cooling fan in the unit finishes cooling, the unit will not switch back on. To get it to work again I have to pull the unit from the dash, disconnect the power plug and remove the unit fuse. Connecting all these back up again and it works until I turn off the engine and the cooling fan stops....etc.
It appears that whilst it is drawing power from the car it works fine, but when all power stops to the unit then it doesn't want to know.
Is there a vehicle setting which is needed to be activated to allow the unit to get power and switch on - thinking along the lines of connecting a VAG COM and activating some detail. Does anyone know and can they help?
The unit is 1T0 035 680H loaded with SW: 4020 HW:61 V9 Maps installed. Manafactured Sept 2012
