Where can I find a online manual for my R50. I find owners manuals online but they all skip the radio.
Thanks.

 

Reviving this thread about a year later b/c now I'm looking for this too.

Or specifically, why would I adjust the "tone line" setting in the hidden stereo menu? (What does it do?). Also what do the various speed-sensitivity volume setting indicate?

Anyone?

 

well, here's a link for the 2006 radio manual. Don't think it's the same as yours, but it's something.

I'm actually replying just to tell how gorgeous your car is!! I've never seen that color before and I think it's really fabulous!! Congrats.

 

Tone Line on my R53 resets all normal settings (balance, treble, etc.) to the middle. Linear, perhaps? Why is this setting there? Who knows...
Speed volume makes the radio louder at higher speeds. The higher the level, the louder.
