Hi,
I've got a RNS 510 C in my car, but have only ever seen the VW startup screen when I've performed a soft-reset. Should I see the VW startup screen every time I turn the ignition on, after a time of xx minutes of inactivity, or only on a soft-reset?
The car is a late 2006 build with a H version CAN gateway, and I drive the car daily so any battery drain problems would have to be pretty severe for me to note an issue I'd imagine.
The firmware version is supposedly a hybrid 2760 (I think - I've certainly got 7 digit postcode recognition), so is meant to not cause battery issues with my early can gateway.
Ultimately, what I'd like to try and answer, is whether or not the absence of the startup screen is indicative of the unit never fully turning off, and thus when I leave my car at an airport for a few days in the near future, I'm likely to need my jump start box in the boot to get home!
Cheers.
