Have MR-4. Radio works but it's not pulling CDs. Mode button not working.

before you press the cd on button keep holding the eject button while you press power on, I know this works for computers etc.

is bad, the CD drive is bad.
you have choices.
1: check all fuses.
2: replace it. $$$$$$
3: get it fixed $$$$$$$$$$$$$$ ($50/hr x4 ? and parts, nah....)
4: dismantle it, and unjam it , clean it, make sure no broken CDs in sided or labels fell off inside, or other alien objects inside, blow it out.(canned air) (silent prayer?)
4: upgrade to a head end with USB port and run USB mem stick with 1000 of songs off a stick the sizes of a Chiclet gum.

id go with #4, upgrades are a big win..

You probably have on your car stereo either a single push button that you press to select the audio source (Radio/CD/DVD/Bluetooth) or 4 separate buttons labeled: Radio, DVD, CD, Bluetooth, respectively. Because a sync operation can refer only to a Bluetooth audio source (phone, tablet), your stereo is in now in the source mode for a Bluetooth audio source. Find the button or buttons for the selecting the audio source and select Radio or CD or DVD (you are already on Bluetooth).

All you can do is remove the radio and have it repaired by a local approved GM radio repair shop.

Your radio may be functioning normally for the emergency alert. Here is an excerpt from the user guide:

Emergency Alert Mode

The Emergency Alert feature can be used to signal members in your

group of your need for urgent help. MR series radios will operate in an

automatic "hands-free" emergency control mode for a total of 30

seconds after activating the Emergency Alert. MR series radios in your

group will automatically advance the speaker volume to the maximum

setting and sound a warbling alert tone for 8 seconds. The alert tone is

emitted from your own radio speaker and the receiving radios in your

group. After the 8 second alert, any spoken words or incidental sounds at

your end will be transmitted to the group for 22 seconds. For the 30

second duration of Emergency Alert mode, MR series radio controls and

buttons will be locked to maximize reception of the emergency message.

1. Press and hold the Emergency Alert button for 3 seconds.

2. Release the button after the LED Indicator glows red and the alert tone

begins to sound. There is no need to continue to hold the Emergency

Alert button or use PTT for your message to be transmitted.

3. After the alert tone ends you may speak into the microphone. Your

voice or incidental sounds will be transmitted. The LED indicator will

continue to glow for the duration of the 22 second period.

4. After 30 seconds your radio speaker will emit a Talk Confirmation

Tone and the LED Indicator will extinguish. Operation then returns to
normal two-way mode.

Note: All Motorola Talkabout EM, MJ, and MR series radios are fully

compatible with the Emergency Alert feature. Radios other than EM, MJ,

MR series can receive the emergency alert signal, but will not respond

with adjusted volume settings, locked controls, or a warbling alert tone.

Users of other radio models set to the same channel and Interference

Eliminator Code will hear a steady tone for 8 seconds followed by the

voice transmission for 22 seconds.

Warning: The Emergency Alert feature should only be used in the event

of an actual emergency. Motorola is not responsible if there is no
response to the emergency alert from the receiving group.

Best regards.

same this happned to me in my 2006 sentra. the volume for the radio is gone. i can tune, its just barely audible/ quiet. weirdly though it sounds perfect when playing CDs. i almost thought maybe it got switched in to mute mode or something. did you figure out your problem?

I have the exact same issue. I have swapped with two identical MR17.2 radios and swapped out the sirius receiver. No change. I even bought a remote thinking I had to have a remote installed to get it to work...still no diff. Have you ever found a solution?

I hope you're in the 4 year 50,000 miles warranty.
the cd player will probably have to be changed. you can try pulling the fuse to the radio. maybe it will reset and work properly. the only downside is it may have a security code that needs to be input to work again. sometimes they write it on a card or in the owners manual.

good luck.

TH-79A Kenwood HT and with the power off, hold down the MR button and the PTT switch, and while holding both of these turn on the power. The HT will come up in the remote control mode with the display indication "RC" on one band and the normal display on the other band.
.
To get the HT out of the "RC" mode just repeat the MR+PTT+Poweron sequence

Hey.. i just had the same thing happen... bought a 1994 Jetta.. radio in safe mode... so i went online and found out.. hold scan mode and the arrows after your preset station button.. then after like 3 secs or so you'll see " 000" on the display.. use the preset buttons.. 1,2,3, and 4 to change the display to enter your code :D if you lost your code go to VW dealer and pull radio out and see service center .. carry VIN code in as well and they can look up your code.. takes like 5 mins and is FREE,,, man i love that word :D
