Question about Car Audio & Video

Hi Skip, I have a 2003 Chev Silverado,I remove the GM RDS radio/disc/cassette player and installed a GM RDS 6 Disc/AM/FM Radio from a 2003 Suburban.It worked once as I tested the player ,loaded 6 discs,theat feature worked ,the radio worked (both AM/FM).I turned the ignition off and then came back a half hour later and it was now posting on the face "Locked".How do I get the bulletin /procedure to unlock it and reinstall the code or remove it.I do have acces to a GM Tech 2 scanner,but need the procedure info.Everyone is giving me the procedure for the other style radios(non-RDS) units with an AM/FM button.There is no AM/FM, button on a RDS unit...It is a rocker switch. Can you help me with this? Thanks, Mike Peters mjpeters44@sbcglobal.net

Lost sound on 2005 impala. radio works. seems like amp problem.


Do you have base or up;level system ?

Table 1: Radio Features
Table 2: Cassette Features
Table 3: Compact Disc Features
Table 4: XM Advisory Messages
The radio receives power from the RADIO fuse in the junction block-right I/P. Ground is provided via G201 and G202. The radio is enabled/disabled by class 2 messages from the body control module (BCM). The radio routes audio signals from the digital radio receiver or the vehicle communication interface module (VCIM) to the speakers and/or amplifier when directed by class 2 messages.
The Entertainment System on this vehicle is configured with an AM/FM stereo radio with the radio data system (RDS) and either a cassette player or a CD player or both. CD and cassette. The uplevel system provides the customer with extended range speakers and an audio amplifier. Satellite digital radio (U2K) is available with uplevel systems.
The following list shows the radios available for this vehicle:
• Radio (ULO) - AM/FM Stereo, Cassette with RDS
• Radio (UNO) - AM/FM Stereo, CD and RDS
• Radio (UPO) - AM/FM Stereo, Cassette with CD and RDS .The complexity of the radio systems on these vehicle is mind blowing .

Your best bet take it to a GM dealer , has features you are unawear of .
DTC B1025, B1035, B1045, or B1055
When the radio is powered up, the radio supplies low level audio signals to the speakers. If the vehicle is equipped with an audio amplifier, the amplifier will boost the signal sent to the speakers.
DTC B1025 Audio Output Circuit
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With the scan tool, monitor the DTC Information for DTC B1025.
Does the scan tool indicate that DTC B1025 is current?

CD no longer works


No. The truck gets hooked up to a scanner. Then it asks what options your vehicle came with. Like bose speakers And What not. Then the GM scanner programs the radio to the body control module. The radio and other computers are all connected in a network. Unless you have access to a gm scanner and gm programming, you can not program the radio. Hope that helps.

My golf mk4 am/fm/mini-disc player comes on but can't tune to any station. Only displays FM 76.0, do I need a radio code? I bought it as used from Japan 8 months ago. Please, I need your advice!


IMPORTANT NOTE:
You must have the security anti-theft code for your VW radio from the car manufacturer, or from a Volkswagen dealer!


You can find the radio code at: http://www.radio-code.co.uk/

The sequence of programming for 2003 VW Golf radio is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
For example: we have the security code "5079". Then:
3. By the no.# 1 key you will set up the first safe code digit. Push 5 times on the no.# 1 button. The "5" number will be setted.
4. By the no.# 2 key you will set up the second safe code digit. Push 10 times on the no.# 2 button. The "0" number will be setted.
5. By the no.# 3 key you will set up the third safe code digit. Push 7 times on the no.# 3 button. The "7" number will be setted.
6. By the no.# 4 key you will set up the four-th safe code digit. Push 9 times on the no.# 4 button. The "9" number will be setted.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed.
The radio is now ready for use!

I have a 2003 Mazda MPV that has the stereo that you could add a cassette deck or MD to...I do not have either, but there is a button for it. I found a guy on the internet that made a chip that plugs into the back of the radio and has a 3.5mm jack on it that will play when you push the cassette/md button on the radio. It is great....sounds just like one that came from the factory.

Hi there,

Well there's lots of possible reasons. The FM receiver portion of the radio is separate from the AM Band receiver, pre-amp, and amplifier sections of the radio. The FM receiver may have simply failed, as well as the CD player portion of the radio. Your car FM needs repair, you need a multimeter to check it or take it to a repair person. Please post further comments for further help or information......

Good Luck!!

Thanks

Will the wireing from a 2005 chev radio cassette


It will work as long as it's for a GM cd radio but as mentioned it will have to be re-programmed by the dealer.

If it's an aftermarket cd player, you'll require a separate module harness with a relay circuit for the airbags and tach information to function. Or you can purchase a re-location kit which allows you to locate your factory radio into your trunk to hold those funtions. The re-location kit is a fair bit cheaper than the module. It's stupid that GM would design a system like that but that's what you'd need.
