I Just Purchased a Cavalier with an Alpine CDM 7861 stereo. no owner manual or slides to remove the slide out head. how do I remove without damaging the stereo?

nb,bnbm

According to the manual follow these steps

While the clock is displayed, hold down the clock button for 3 seconds.
Time indicator will blink.
Press the ct button to set the seconds.
Press the H button for the hour.
and M for minutes.

Time indication will stop blinking 5 seconds after the ajustment.
Then the time will automatically be set.

Just in case I will include the link to the manual for other operations.....

Check for a "jammed" button. They use a little rubber membrane behind buttons and over time they do wear out. It is possible to push a button on the corner, make it shift enough to jam behind the faceplate & hard to see. Just push the button and see if it pops back like the rest of the buttons on the unit. If it still has a problem, post a comment and I will help you some more. Hope this helps

typically music burned from a computer using the windows media player will play in almost anything. format should be + or - R

WMA format plays in just about anything

my solution is, that you so called experts don't know squat, so you try to get people to pay
19.99 a head to set stations on a stereo

Were you guys able to get this to work?????

remove the face and then the trim ring for face you should see 2 little pins on either side of the radio slide them up and it should slide right out

The only possible installation problem could be the illumination wire on the head unit. If this is hooked to a 12 lead it would dim the backlight. Try disconnecting the orange wire if it has one(I'm not sure if the 7834 had a dimmer lead). If that doesn't fix it the head unit will have to be serviced.

Make Sure the remote wire is connected from the radio to the amp, its normally a blue wire. Here is a picture of what the setup should look like.

Same problem here. It was every now and then it would happen but now its constantly. It aggravates me and I'm gonna have to buy a new deck because I don't know whats wrong
