1) Startup order after reboot, say if SD played last, make it start first and continue the last song. If that's impossible, at least play radio or CD so that we don't have to wait 90 seconds to be able to hear music. Preferably, leave the choice up to the user.
2) Don't totally mute the music when giving Navi voice commands. Attenuate it, again leave the choice up to the user. Edit: I think it may already be there, page 144 of the manual, I'll have to test that out.
3) Allow us to have something other than black as the background for A/V source playback. I'd rather have a nice red or blue background than just a greyish/black background with white letters.
4) Finally, please allow us to be able to change the system settings without the parking brake having to be engaged. I know, this last one may be a stretch, but the top 3 should be a piece of cake to implement.
Thanks in advance, your satisfied customer.
