RE: Radio problems
The wait indication comes on if the wrong security code is entered too many times of other related activation problems. Manual indcates you have to wait 24 hours for a rest to occur if too many codeentry attempts occur. I have been able to disconnect battery or radio fuse and then renenter the proper code and the radio will turn on correctly. See what www.alldatacom provides below for my car:
Coding Radio
Antitheft System
The Mercedes-Benz AM and FM stereo radio with cassette player and CD compatibility is fitted with a built-in system designed to help render it inoperative in case of theft. If the radio or battery is disconnected, the radio will be automatically disabled. To indicate this state, the word CODE will appear on the radio's display. To render the radio operable again, the correct four-digit code must be entered into the radio via its numbered station recall buttons. A code is preassigned to each radio and supplied to the owner on two wallet-sized cards.
Recoding Sequence:
To recode a radio, follow this procedure: [*]Turn ignition key to lock position one.[*]Turn on the radio. The word CODE appears on the display.[*]Enter the first digit of the radio's antitheft code as it appears on the code card. The word CODE will disappear and the first number that you have entered will be displayed.[*]Enter the rest of the antitheft code. Each number will be displayed when it is keyed on.[*]When all four antitheft code numbers have been correctly entered, radio operation will resume. The station stored at push-button 1FM will play.

Incorrect Code:
If an incorrect antitheft code digit is entered, continue to enter numbers until four are displayed. The word CODE will appear again. The system allows two more recoding attempts. After the third incorrect attempt, the word WAIT is displayed. A period of 15 minutes must pass and the word CODE must again be displayed before recoding can be successful. The radio must be left on during this period. This measure is meant to prevent a thief from recoding the radio by randomly entering numbers.
If the correct antitheft code has not been entered after three separate attempts -and therefore after two 15 minute wait intervals- the radio will lock for 24 hours to prevent any further recoding attempts. The radio must be left on during this period in order for it to reenter the code mode.
Code card should not be stored in the glove compartment. During vehicle service at an authorized Mercedes-Benz dealer, we recommend that you leave one card with your service advisor. Thus, if the battery is disconnected, the service advisor can recode the radio before the car is returned to you.
If the car is equipped with a Mercedes-Benz antitheft alarm system, the alarm will sound should the radio be removed from the console while the alarm system is armed. If you have difficulty reprogramming the radio or if the reprogramming function fails to operate, please contact your authorized Mercedes-Benz dealer.
