Hello, i recently purchased a RNS 315 with DAB and Bluetooth for a decent price to upgrade from the standard SWING radio that came with my 2011 fabia elegance. I have read about the CANBUS issues and how incompatibility would lead to a power draw issue that could lead to a flat battery, I scanned the CANBUS using VCDS and my version is 6N0 909 901 which i think is the older part and has issues with the RNS 315. When i install the RNS 315 it does seem to turn off when i take the key out of ignition, or atleast the screen turns off as i can still turn it on after using the power button, the MAXI-DOT screen does seem to recognise is as i can access navigation and phonebook tabs, the Bluetooth connection to my phone also turns off when the ignition key is taken out. I am not sure however if i can keep it installed as i fear a flat battery happening from a power draw problem as the radio does not recognise the car being off. I have purchased a "1.6- 2.0 CANBUS quadlock emulator" to hopefully test it out and prevent it from causing a flat battery hopefully. Has anyone had experience in this subject and can offer any information or help it would be appreciated.
