Hello, Im upgrading my head unit to the later RCD330. I'm aware I may need to change the CAN Gateway in order to stop the battery drain.
HOWEVER, I've also read that at some point they crossed over to the new CAN Gateway and as mine is a later MK5 I may already have this. This would be ideal as although the cost of upgrading isn't the issue, I don't have access to VCDS so would need to find someone....
Is there anyway I can check what CAN Ive got before I start? Failing that, once the Head Unit is installed, is there anyway of knowing wether its draining the battery other than waiting for the battery to die? Will it turn on with no ignition if the CAN Gateway is too old for example to confirm that the upgrade is needed?
Thanks
