I just finished installing new speakers and a new head unit - Sony CDX S2210. When I try to turn it on though, nothing happens. I can insert and eject a CD, so it has power, but nothing comes up in the display and the CD doesn't play.

Do I just have a bad faceplate or is it more likely I screwed up in the installation? (My first intallation.) The only thing I can really think of is that it isn't properly grounded. The previous stereo (not factory, something put in by the previous owner) had the black ground wirer running into some unknown brown wire. I just grounded mine to metal in the dash.

 

If the unit will take a CD then it is doubtful the installation is messed up, obviously you have power and a good ground. if the faceplate is removable, remove it, remove power and try re-powering the unit back up. The unit may have a reset button as well, try it. FWIW stay away from Sony for car audio products, they make really nice TV's though.

 

Yeah, the faceplate is removable. I've tried popping it on and off. I've tried pressing it harder against the unit, and I've tried the reset button. When you say "remove power", do you mean go back into the dash and disconnect the power wire?

 

Did you use a harness to adapt the radio to the factory wiring harness or did you start hacking on wires?

 

If the head unit is powered by sources other than the ignition switch then yes remove power. Doubtful this will have any effect if the reset switch didn't but worth a try. As an after thought does your head unit have a "valet" mode? Some units have this to disable the unit when the vehicle is being driven by persons other than yourself, ie; a valet attendant or service rep.

 

callmej75 - I spliced the wires.

 

Sounds to me you have some wires connected wrong. Can't help ya much on this...if it was me I would reconnect the factory harness and go buy a harness to adapt to it. All wiring diagrams are on these harnesses and are very simple to hook up and don't cost alot.

 

unfortunately, there's no factory harness left. whoever installed the last stereo got rid of it. I'll just have to experiment I guess....

 

hey i just went throught the same thing, the best and only good way to do it is to reconnect the factory harness and use a aftermarket adapter, you can order the factory harness from toyota or get it from fry electronics like i did, also if you have a factory amp bypass it and use the harness behind it. If you have any more questions feel free to pm me

 

by the way the brown wire was a propper ground in my case, but if use a test light to double check.

 

if you dont have air bags you can use a test light.

if you DO have air bags you will deploy your air bags if you find the wrong wire - I watched our lead installer make that mistake....lol And I razz him daily about it!

Honestly that deck from last year is a POS. We have had more problems with those sonys last year than any other line of deck including jensen so this year we have been pushing customers away from those two decks..... Swing by a local CC and have them just plug in a sony 5710 and see if it works. If it does then you have a crappy deck. If it doesnt then you have wiring issues.



EDIT:

as long as the yellow wire has 12v at all times,
as long as the Red wire has 12v only when the key is on 'acc' or 'on'
as long as the Black wire has ground, the face should work 100% of the time on 100% of all decks...

illumination and dimmer wires shouldnt need to be hooked up, and 99% of the time we done hook them up anyhow.

 

Sounds to me like the very best thing that you could do would be to take that POS out of your ride, back to the store or local pawn shop and trade it out/sale it for something better and solve all of your problems altogether.

 

ps - also be sure to blow off any dust from the contacts on the faceplate and the deck shouldnt be an issue but never can tell...


PPS - I JUST REMEMBERED! Check the fuse on the backside of the radio that the Sony Molex holds in when its plugged in. If that fuse is blown replace it!

 

FWIW ... If the unit sucks in the CD and you can eject it the head unit is getting power and has a good ground so you can eliminate those issues. Vehicle wiring isn't gonna impact what is happening to the faceplate (other than the dimmer option, best left disconnected). The faceplate NOT showing a display pretty much sums it all up, the head unit is hosed.

 

OK, I went through everything, recchecking wiring, etc... even got a new head. Anyway, after all that, I finally found my multimeter, and it turns out there's no voltage on the accessory cable. I get 12+ off the battery cable, but nothing on the accessory cable. I checked the fuse for the radio in the fuse box by the driver, and the accessory fuse under the hood and both are fine. Is there any other reason I might not getting any voltage on the accessory cable?

 

Could you possibly have it hooked to the wrong wire?

 

It's possible my wiring diagram was wrong I suppose. According to what I downloaded from InstallDr, the gray wire is supposed to be the ignition power. I guess I can go ahead and check the voltage on all the other wires...

 

try seeing what www.the12volt.com says for your ignition power wire

did you check the fuses with a DMM? Thats the best and fastest way. You either got the wrong wire and the accessory wire is attached to something else or not attached or a fuse is blown.

Did you check the fuse that is on the backside of the sony deck?

 

Still haven't solved this problem yet. At this point, I think I'm going to just pay an installer to do it. (I think the accessory wire must be burned out somewhere deep in my dashboard, and I just don't have the ability to fix something like that.)

Problem is, now I have this road trip coming up, and I'm out of time to get it fixed in a shop. If I don't have a stereo on my road trip, I'll go nuts. So, I was wondering - can I fork the battery wire so that it also plugs into the accessory wire? This will mean my stereo is just always on unless I turn it off, I know, but will that work as a temporary fix?
