Radio Service Mode

For pulling out a nice Service Menu out of the Radio, do the following:

Switch the radio on
Push "TP" for at least 10 seconds
A "Service Menu" will appear. You will be informed about
Serial Number
SW Version (mine is from 15/94)
Seek Level ("I" for reception of strong radio transmitters, "II" for reception of all radio stations)
GAL (Geschwindigkeits Abhaengige Lautstaerkeregelung - speed dependent volume control). Set it to 1 for small volume increase when driving faster, and set it to 4 for even more volume when driving faster. Mine is set to "1" and still too much).
DSP (If your car is equipped with the HiFi Professional DSP, you will find an "1" here. Otherwise a "0" (like mine).
FM (some information about the radio station you are currently listening to. Includes also quality of reception.)
To get back from this menu, simply switch off the radio.
