An audi dealer may have the code on record but as this can be changed by the owner(or anybody else)anyone with half a brain would have written it down inside the service booklet when bought new..

Stock radio reception

There were 17 entertainment systems used in the 2005 Audi. It is possible that the aftermarket antenna was connected directly to the radio, bypassing the Audi antenna modules.

My Audi A4 2.8 battery went dead, and my radio went on safe mode. Do anyone knows the code to turn it back on ?

You need to contact Audi Dealer and provide your VIN# (It's an anti-theft deterrent issue) TIP: when you get the code, write it down in your glovebox w/a Sharpie (just in case)

Car battery died completely and was replaced with a brand new one. Now the CD player does not work at all. No time is displaying, radio does not turn on, no light to the display screen. I was told by a...

Yes. Radio units have a security measure that shuts them down when power is disconnected. With proof of ownership, your Nissan dealer will provide the proper code and instructions for resetting the unit. If you purchased the car new I suggest that you take it to the dealer where you purchased it, and don't let them charge you for the information/service. If you are not the original owner you may need to reimburse the dealer for time spent in obtaining the information for you.

My 2005 Odyssey was repaired after rearending another car. Everything is fine except that the radio and clock don't work. When I turn it on, the word "Code" appears. What should I do?

Look through your manual and see if it includes the code for your radio. What happened is the repair shop disconnected your battery which reset the radio. It's a safety feature in case the radio gets stolen. If the manual does not have the code, you'll have to bring it to a Honda Dealer with all the documentation stating that you own the vehicle and they should be able to provide you with a code.

You may have the clock and radio power leads reversed. Clock needs to be on a line that is hot with key on or goes to a lead that is only hot with key on.Same goes for lead for power antenna...don't need power there unless car is on. Don't forget...I'm not there so I can only make an educated guess.
Good Luck

How to input radio code for my s reg audi a4

Okay here are your radio options. Audi will charge about $125 to extract the code from the radio but you may try this first
1. Look in the owners manual. If the car has the original packet with the owners manual and other pamphlets, it is likely that the dealer wrote the code down and put it in there in the glove box.
2. Audi puts the 4 digit radio code on a sticker in the spare tire compartment in the truck. It is a four digit code that will begin with 1 or 0.
3. Audi will use the code 1111 as a default code on rebuilt or replaced radios. try that first.
4. still no luck.... go to the dealer and pay the $125 and have them extract it.

Cleaned battery cables and radio is safe mode. purchased the car used dont know the code.

By now you probably solved this problem but here it goes. Once power is disrupted to the radio the radio goes into safety mode. At this point only the dealer can give you the code to restart the radio. The radio must be removed to gain access to the series of numbers on the tag. The dealer can input these numbers into the computer to retrieve your code. Once you have the code you can write it down and keep a copy (in multiple places) and also put it on a piece of tape and put it under the cover of the armrest or anywhere else that it is not visible. Any time power id interupted to the radio this will happen, even if the fuse is removed by accident. If you are taking the car for repairs always have that number if you llike your radio.
