This is really doing my head in but I cant for the life of me work out how to change the default volume on my BOSE PHILIPS in a 1999 Elite. I have to turn it up after every time I restart the car.
I found a work around, by turning if off before switching off the ignition it will then come back on at the same volume, but I normally forget to.

Does anybody know if and how it can be done?

Cheers
Phil
