    I have an MR-4 that has the same problem. The power comes on but the display just says "tel". I've done a hard reset and the same thing happens. Any suggestions?

    I have this model on our spa. I just installed but the provider did not give to me an owner's manual. How do you complete the 'hard reset' mentioned previously? I have NO POWER showing at all.

Is there an adapter I can purchase to be able to play an IPOD with my alpine cde 9841 car cd receiver stereo?


Your headunit doesn't have the option of a plug i Ipod cable, The only way to use it with your stereo is to get an FM Transmitter and you tune into the ipod through the radio.

I've got VW Passat b6 2006. Rosen-VW0710-H11 is installed in it. When I try to play DVD (no matter audio or video) system displays message: "Password Fail". What can be the reason of this...


I would recommend resetting the Rosen unit. This is done by entering the "Menu" and pressing "Settings". From this screen, you select "Keypad" in the top right corner of the screen and then enter "7-5-2-3" and press "Enter". This should erase any code for Parental Control (levels 0 - 8). Also, the Rosen product states to only use "Store bought media" for CD's and DVD's meaning that it won't play all 'burned' discs. Hope this helps.- Elliot

You need to reset the CD player. Remove the front panel and you will see a tiny hole in the middle of the panel of the unit mounted in the dash (i.e. without front panel). Gently push a ball point pen or pin in to press the reset switch.

My pioneer car stereo DEH-P77MP won't play cd's anymore. the radio still works, but on the screen it says cd error AO or A0. i was wondering what problem this code relates to? hope you can help,...


This is a common error with these units when they get dusty from putting dirty disks inside the drive. Just go to your local staples and or walmart and get a 5 dollar disk player cleaning kit. It looks like a plain cd but has small fibers that come out of the bottom of the disc that clean the laser as it spins and tries to read it.

I attach my new ipod touch to my JVC car stereo and the screen displays CANNOT PLAY. What is my problem?


Are you attaching it via usb on the deck or aux? Because if it is via usb the touch is probably not supported.

My car stereo shuts off while driving and playing


if you have had the head unit for long, it might be over heating and going into safe mode so it doesn't get to hot. This happened to my amp and i never did anything until it stopped working all together. so my guess would be just to get another head unit or get some type of cooling system.

CD Player not working


There may be dust inside the unit on the laser. Try shoting some compressed air in the CD drive area to clean out. Also, ensure that the CD surface is clean, and try a different factory made audio CD. Sometimes CD players have problems reading "burned" CD's.
