Question about Alpine MDA-7755

1 Answer

About scheme hello. my name is mr. Eugene Belousov. I'm writing this massage in order to get a scheme for Head Unit Alpine MDA-W779JB. I have purchased this item in Japan in 6/28/2000. Currently it has problems in functionality. As we do not have service center of Alpine company in Ukraine, i have to bring it for service to another place. However, this service center reqires me to provide a scheme of this model, because they cannot proceed to fix this item without scheme. Please, kindly help me to get the scheme for model Head Unit Alpine MDA-W779JB. Looking forward hearing from you. Best Regards, Mr Eugene Belousov.

Alpine head unit CDE-9870 will not play sound through speakers of a 2003 pontiac vibe. what could be some issues to cause this?

This generation of Vibe may have the upgraded audio system installed from the factory. In order to get the audio from an aftermarket radio to play through the factory amp, the factory remote turn-on lead must be located. If you are using an adapter harness, it may have the wire installed, just attach the blue/white stripe wire from the Alpine to the blue or blue/white stripe wire on the aftermarket harness adapter.

Dont want to lose stork controls and trip computer on fiesta st??

You have to bypass your entire factory system, it takes some customizing and careful installation, too much information to write over Fix Ya advice, phone or actual physical support in a car stereo shop is your best bet.

Good luck my friend.

I am getting a DC error on my alpine cde-102 head

Hello christo12385,

The DC error is most likely caused by a shorted or grounded speaker wire. Check all speaker wires, correct the problem, and then go into the sound setup settings and reset the POWER IC to ON.

Hope this helps.

Ipod to alpine CDM-9821

Hello andrewbheber,

Your head unit is an Alpine "M-Bus" unit and has a proprietary connector for the AUX input. It requires a special cable from Alpine, the model KCM-123B..

Here's a link to the product. Click on the cable itself to see an image of what the connector on the back of your receiver looks like.

Hope this helps.

Connect alpine 7874 to alpine powered sub

You need to run the RCA cables from the head unit to the sub for the audio signal, and possibly a turn on wire (the blue one on the back of the head unit), unless the sub has an automatic power feature.

The sub also needs power and ground wires attached, but those do not connect to the head unit. Power should be run directly from the battery with an inline fuse, and ground should go to the nearest good ground point (Trunk latch, seat bolt, etc).

MDA779JB Car Stereo

The manual appears to only be available in Japanese. Sorry. I have however been able to badly translate the japanese for the clock setting - check page 50 of the manual (page 17 of the pdf file). It reads: To set the Time: keep pushing "Disp 1" until you get the time set mode (possibly means 'hold down' not keep pressing) press "Clk Adj" for 2 seconds or more and the time blinks If you push "H" within 5 seconds you can adjust the time. push "M" to change the values, then if you leave it for 5 seconds it is set. The first footnote says this directly translated - sorry I have no idea what they mean on this one (i think carries means saves in this case)- "When liking to adjust to time signal, when ?the time? ?, CT? is pushed after the setting ?amount? indication becomes with ?00?. ?: When indicating which exceeds 30? when ?CT? is pushed, ?the time? it carries" Second footnote says this; You can do this procedure starting from any mode. Hopefully, with the pictures in the manual to show you which buttons they are talking about, this can get your clock set. If so, then if you want to try and translate other parts of the book, just copy and past it bit by bit into;|en seems quite good as these things go. Hope this helps, if not please ask again and tell me what you got trying the above procedure. :)

Alpine Ipod/Stereo Error 1 message

my alpine cda 9856 only displays that message when my ipod dies. so your ipod pobably dies then the head unit recharges it enough in the time your resetting it that it can play again. :)
