I had the same problem in my 2002. The nav plays through the phone input on the stereo. you can set the phone volume from within the radio service mode. from a previous post:

-----

I broke the code last night on my 2002 M5. Here is how I got the service menu up. I have a car that was built in week 40. 10-1-01.

Get in car close doors, turn key to Position 1 or 2, hit the accept on the Nav system and make sure the radio is off.

pull the key out and put it in Pos 2.

turn radio on and hit the "Select" key and hold it until the display changes or flashes and becomes the menu screen.

I then turned the right hand computer knob one position right or left and

You are in: You now see the service menu appear with the radio serial number.

Use the < > keys to scroll through the functions and the 1 and the 2 keys to make selections for each setting.

You see (not in this order):
Serial Number
Software Version
GAL (mine was set to 2, I changed it to 6)
FM station info
Man
DSP
TP volume
Country

Turning the radio off saves the changes. I also found all my preset radio stations were lost and had to be reprogrammed.

----

scroll to TP volume and increase it a few clicks. Turn off the radio, turn it back on, and try the nav again. That should do the trick. if it doesn't let me know and I have another idea.

I fixed the same problem on my 2002, but I made two changes at once and I'm not sure which one did it. The instructions above seemed the most probable.
