SERVICE MODE FUNCTIONS
NOTE:

Functions vary between models.

Serial Number:

Displays the radio serial number.

Software Version:

Displays the radio software version (Calendar week/Year/Version).

GAL: Speed sensitive volume control.

The speed sensitive volume control can be adjusted from level 1-6 using the 6 preset audio buttons. Radio
volume increases more at level 6 and less at level 1 (road speed dependent).
Vehicles equipped with DSP do not use this feature.

Field Strength & Quality (F/Q)

: The station currently displayed can be assessed for field strength and quality.

An 'F' number (i.e. 1-15) is used to indicate the strength of the signal being received by the radio. A high 'F'

number indicates a strong signal.
A 'Q' number (i.e. 1-15) is used to determine the quality of the radio station broadcast including both the audio
and RDS signal if applicable.

DSP

: Digital Sound Processor

This function provides information about whether or not the vehicle is fitted with DSP. (1=Yes, 0=NO)

TP Volume

: Traffic Patrol

Provides adjustment for traffic report minimum value. On some vehicles this setting can affect the NAV volume.

Refer to Service Bulletin

B84 02 03.

AF

: Alternative frequency tracking setting. Not used in US.

Lex, the speed sensitive volume has 6 settings, maybe the lowest one is ok for you? In RAD module (radio module) I do not recall disabling the GAL was an option but the setting the GAL to 1 through 6 - was...

What are you trying to accomplish by removing the speed sensitive volume and how is it on the way of your future installation?

I dont think it does but heres a link with my exact cable. you have to modify it to work with inpa and read battery voltage:
My DIS/INPA/SSS/CARSOFT/NAVCODER Interface. - Bimmerforums - The Ultimate BMW Forum

or am i doing it wrong? i tried hooking up to inpa yestrday and nothing happened.

my cable looks the same, but it was working on E53 right out the box... i just needed to make sure i use the right COM port first... I did not open the cable so i do not know if it was soldered or not...

Your The Man Term!

The Link JCL provided was for older radios and I couldn't get it into the service menu. I used your updated info for my newer Gen. Radio using the Select button and it worked perfectly. I lowered the GAL from it's inital setting @ 5 down to 1 and did a sport mode test drive It worked like a charm I can't hear the volume increasing at all anymore.... Now I can start pulling my interior and run some 1/0GA

Thanks a million kind sir!

how are things coming along?

BTW, the GAL changes volume around 40 MPH and the next step is around 80 MPH... i don't know if there is one more step - if there is, it would be at 120 MPH, naturally...

It's funny you mention that term. I was doing 120 today and I didn't notice the volume increase at all J/K It's nice to know those trigger points though. Thank you for that.

I will be doing the install this weekend. I will post pics of the adventure as it unfolds.
Here's a shot of my woofer. It's 70lbs. of sonic bliss... Elemental Designs 13Av.2



It's pretty Beefy



And I figured u guys might dig the box.... 2.4 cubes, Tuned to 32Hz, Kerf Port, Recessed mount W/ the custom Roundel @ Raised BMW lettering. All internal corners 45'ed with lots o' bracing
