Monepit,

Are you getting any functionality issues: Is the CD changer working properly? Ensure the steering wheel switches functional too.

Other than a malfunction in the head unit causing the message, you might try ejecting all disks, see if it clears, and then re-insert the CDs until the error message appears. If the error message is present no matter what # of disks are installed, the laser may be dirty. There are commercial cleaning products that may be of help.

Thanks CC. We took a trip this weekend and got a book on CD I put 3 disk's in and it played the first one fine. The rest of the trip it would play once then I would stop the cart and on start up it would say CD error. after a few times I said heck with it and put it in the DVD slot and finished the trip. Now this week it has played whatever disk I choose every time. I don't know what the problem was. I'll let you know if it act's up again.

Yes, CD Error message.
I hit the eject button and the unit started to eject the CD the stopped before any CD came out.
I took it to a dealer and they pulled the unit (they had to pull the steering wheel to extract the unit?) and the told me they would have to send the unit to a third party for 'replacement' as they do not repair or extract CD's stuck in the unit.
I think their quote of $1600.00 is a little pricy to fix and lube a CD player!(and that's not including the garage fee for pulling and then re-installing the thing)!
Does anyone know of any other options.
I now have a big hole in my dash, my whole unit sitting at my house, a crooked steering wheel that was not put back on straight, and a horn that now works intermittently, HA.
I need any info and/or contacts to get this resolved.

Sorry for the delay in getting your post approved.

When you first join you should post in the new members area. That way the moderators can easily find your post and approve it.....most of the time.


YOUR RADIO--- If CC sees this post he may know from his shop manual how to easily remove the CD now that the unit is out and on your bench. There should be a manual release button that will allow the CD to be ejected and removed from the unit.

If not I would see what a car radio place would charge to remove it for you.

I hope this issue gets resolved for you soon.

Regards

Jerry

There is NO need to remove the steering wheel to remove the radio. It's a very simple process involving a t-15 torx screwdriver, a plastic spatula. and a 10mm socket as the only tools. Takes 15 minutes or less.

PM me for a link to pictures and directions.

Unless the tech was trying to troubleshoot a suspect steering wheel switch, there's absolutely no reason to pull the steering wheel to remove an infotainment unit, and even less of a reason to re-install the steering wheel wrong.

Service Managers were created to address workmanship problems like this. I suggest you drive the car back and let him check it out. Mention the new horn/safety issue and I predict you'll have it fixed fast. --And maybe a free, goodwill oil change!

Did the dealer include a customer satisfaction card to fill out with your invoice? Award-winning dealerships do. Service managers get all kinds of awards (like Hawaiian vacations) for superior service by competing with area dealerships, and it's based on the ratings of the feedback cards customers submit.

The Service Manual treats the head unit as a sealed component. If bad, replace. You would need a Denso Repair Manual to dig in and look at it.

As mentioned, removing the head unit is so easy, a cave man can do it. (No offence to any Neaderthals who might be following along. . . )

I poked around online today for new OEM head units and they're very pricey-- one quote was >$3300, which is about as expensive as getting a liver transplant in China nowadays. With a core charge, $1600 may be about right. Still, you can purchase a really nice, full-featured, head unit with a better nav system including installation for less. Be aware you may lose some steering wheel switch functionality and the existing Bose components might have impedance matching issues.

And if this post wasn't long-winded enough, there's another option:

For $700, you can also buy a used head unit off eBay.

Details here: http://www.ebay.com/sch/i.html?_nkw=....c0.m270.l1313

Since it's from a 2007 model, it won't have DVD watching capabilites while driving like the earlier models. Also, be aware that when a different GM head unit is installed, it will require a dealer's Tech 2 to program so it will work with the built-in Theftlock feature.

Hope this helps a little. Good luck!

Is a Tech 2 required?

Hey Guys:
I finally got my radio back from the car stereo shop.
The place THEY sent it to had to send it out to a Denso shop.
I looked at the serial numbers on the CD changer when it came back and they matched.
But...on the head unit there appeared a new sticker that said '04' that wasn't there before.
I tried to adjust the EQ settings to get back that killer Bose sound to no avail (sounds like a 'transister radio').
I also, tried to 'code in' to play a DVD while driving...no luck there.
After talking with the shop that I took it to, they said this was the exact same unit that I dropped off.
Unhappy, I got the phone number to the second shop and was told the same thing (have not yet been able to get the number for shop #3 Denso?).
I told them that this thing has NO sound quality and the DVD code doesn't work any more.
I was told by shop #2 to take it to a dealer that has a Tech 2 machine to set-up the unit, because they had reset all the defaults when they had it?
Is this true? Will that put the Bose quality sound back in it and, will that again allow my passenger to watch DVD's going down the road?
Or...did my head unit get switched out when I did not ask for that to happen?
I'm really frustrated and could use your expert advice.

Unless you're able to contact the Denso tech who actually worked on your head unit or access the Work Order, any information you receive from the numerous middlemen involved is speculative hearsay.

Sadly, techs that can troubleshoot to board level components are getting harder to find. Besides, it's common (and ultimately cheaper -depending on the device) to replace a circuitboard or subassembly -rather than taking the time to troubleshoot, repair and test it.

Externally, I'm sure it's the same unit you dropped off. Your infotainment head unit's faulty board may have been swapped out along with the encoded PROM containing the vehicle's VIN. Newer versions of the infotainment unit do not allow for DVD access while the vehicle is in DRIVE, as you probably know. This is speculative hearsay on my part -but at least I'm up-front about it. Once the word got out that we could play DVDs with the 1791 code, that capability went away faster than a super model's stretchmarks after giving birth to quintuplets.

A Tech 2 scan tool has the ability to display the operating parameters of the infotainment system and determine if your amp is producing proper channel outputs, but as far as "resetting" the system, (another reason I suspect someone swapped out the main board) if it doesn't work properly now, I don't know how a Tech 2 is going to change that. It can program a VIN, but you already have that working for you--otherwise the unit wouldn't power up.

It could be something as simple as an internal connector in the head unit not being connected properly. --Peering inside there would violate whatever warranty you might have. Symptom-wise, it doesn't sound like it's working properly with the amp or it's DSP settings. I would check the head unit's external connectors, and if they're connected properly and it still sounds like an aftermarket North Korean Premium Yugo sound system, take it back to the sound shop you originally had do the installation and sub-contracted repair work.

ccclarke.....one of the absolutely best posts I have seen on this forum...you are right on target. Thanks for being clear, concise, and even adding a bit of humor. I too have the dreaded CD ERROR message, even tried a replacement unit I bought on Ebay, but had same problem. Removal and installation is very easy, if you are careful with scratches, etc.. I relunctantly decided I could live without a CD player. Thanks again for your post.
