Where did you adjust the volume? Adjusting it via Settings-menu is not enough, you need to adjust it via Info-button's nav-min adjustment. If you already did that, then using a potentiometer or fixed resistors is the way to go.

Easy: there is a twsted pair of wires on the nav blue plug. Normally blue/ brown and blue/red. On some cars yellow/brown & yellow/red

red stripe is signal
brown stripe is ground

Fit around a 1 to 10k-Ohm potentiometer

solder one end of pot to brown stripe wire
Cut red stripe wire, solder nav end to other side of pot
Solder radio module end to wiper of pot.

You get the message stating no LNG language files can be found, because no LNG language files can be found !!

Copy all files in the NavCoder zip file into the same directory

Make sure at least one LNG file exists

If it still doesn't work, email me.

Hi TJJ,

Yes, I have done both already.

1) Adjusted to bare minimum via Nav Volume settings. Done.
2) Adjusted volume via Radio Service Mode Info Button. Done.

Still too loud : (

Looks like potentiometer is the way to go.

Thanks.

Dan

Excellent info. Thank you!

Wow, you folks are just like the nice people we have on our M5board.
Very helpful!

Many many thanks!!!!!!!!

I will order the NavCoder next week so I can turn off the light bulb fault messages on my M5 and my wife's 330ci (I converted my license plate bulbs and 3rd brake light bulbs to LED's.)

Thank you folks again for everything.
