Audio/Bluetooth/PDIM FAQ

[UCF w00t]

This doesn’t cover everything but I tried to get the basics in. If I haven’t answered your question please search and it may have already been answered in another thread. If you feel I’ve missed a common question or have an error or clarification above, let me know!


What audio devices does my car support?
All models come with the Auxiliary input. This allows you to plug in any music playing device that can connect to a pair of normal headphones. You’ll likely just need a male-male 1/8th inch stereo cable. If you have a 1LT with the C&C package, 2LT, or 2SS you have the PDIM module (explained next). And of course there is that slot you can stick a CD into.

Is there a CD changer available?
No. You can, however, create an MP3 CD. Basically you burn your MP3 files onto a CD as data instead of as audio. Through the magic of compression, this will allow you to fit about 15 albums (depending on track length, etc) on a single CD.

What is this ‘PDIM’ module?
The PDIM (Preferred Device Interface Module) allows you to directly connect many USB-compatible devices to your car to play music. It also allows you to wirelessly play music from a supported device via Bluetooth.

What devices are compatible with the USB port?
Most USB flash drives, 5th Generation iPods and newer, Micrsosoft Zunes, and many “PlaysForSure” devices made by other companies such as Sandisk Sansa players. For more details on which MP3 players are compatible, see this PDF. Note: many older iPods will work however they will function as USB flash drives and not as an iPod.

Is there a difference between the various USB devices?
In one word, yes. For the most part, the newer iPods work just fine. However other devices have some issues that are not fixed by any currently available software update. This is because the indexing is handled by the iPod but the Camaro maintains the index of songs for other devices.

What issues are there for non-iPod devices?
Each time the car starts, the PDIM re-indexes the device. Depending on the number of songs and layout of files, this may take anywhere from a few seconds to a couple minutes and you cannot change tracks or browse the device while it is indexing. Also, the Camaro does not remember the previous playlist or “random” setting. When the car starts, it will continue playing the previous song however after that it will continue in alphabetical order. Finally, there is a limit of 2500 songs on a single device. Again, newer iPods do not have these issues.

What file formats are supported on USB flash drives?
MP3 and WMA (non-DRM).

Are playlists supported?
This seems to be rather hit or miss. I have personally been able to get one working but it seems a bit tricky. Your mileage may vary. I believe playlists work just fine on iPods.

Is DRM music supported?
Like playlists, YMMV. It is dependent upon the device you are using to play it. Some PlaysForSure devices are supposed to support this. This should work fine on the supported iPods. Reportedly, Zune Pass music with the ZuneHD does not work.

Can I buy the PDIM module for my 1LS/1LT/1SS?
Yes! Some dealers may not be very good at getting it installed but yes you can. The actual install is relatively trivial however the head unit must be updated by a dealership in order to recognize the PDIM. This is the same hardware that’s included in the other cars but does not add the steering wheel controls.

So what’s the deal with Bluetooth?
There are two separate Bluetooth modules. One is in the OnStar unit. This is what allows you to make and receive hands-free phone calls. It is included in the same cars that include the PDIM module. It acts just like a regular Bluetooth headset. The second one is part of the PDIM module. This allows supported devices (Smartphones for the most part) to stream music over Bluetooth to the car’s speakers. This is very similar to plugging your device into the auxiliary port in that the music is controlled from the device and not the head unit. However, some devices may support track forward/reverse from the head unit.

If I buy the PDIM module will that let me make phone calls via bluetooth?
No, it will not. As stated above, there are two separate modules. You will, however be able to play music via Bluetooth over your car speakers. BUT, you can swap out the OnStar module for the one that includes Bluetooth and add it that way. (thread explaining this)

My PDIM doesn’t seem to be working!
Make sure the device you’re plugging in functions. If it does, even if there’s no music on it the car should display “Unsupported device”. If you continue to have problems, take it in to your dealer as there may be a loose connection or the PDIM could need to be replaced.

I have one of the early Camaros, is there a software update available?
Yes, the first cars had software version CC. There was a version CD available to dealers briefly. The current version CE began shipping from the factory sometime in July 2009. This fixes some issues mainly with iPods and some stability issues here and there. You can obtain this by visiting your dealership and asking them to install it (it is covered under warranty). They may have trouble finding the update so as with many other things, YMMV. It is available and several people have been able to get theirs updated.

How can I tell what software version I have?
While on the screen for a USB device, press and hold the menu button for a few seconds. A screen should pop up with the HW and SW versions.

Where are the 9 speakers in the Boston Acoustics system?
The math is a bit fuzzy but…
1 in each door
1 tweeter on each door
1 center speaker
2 rear speakers which include a main speaker and a tweeter (totaling 4 speakers)

Can I replace the head unit?
Since the head unit is integrated into a lot of functions, you cannot truly replace it. However, you can relocate it and replace it with a 2nd head unit in the dash. This is a very tricky proposition and requires a great deal of time and effort.

Wow, thank you! I've been wanting to post something like this, but you did a fantastic job. The only update I have is that the PDIM actually stands for Preferred Device Interface Module. Not a big deal, but just thought I'd give you the official name .

[UCF w00t]

"Preferred Device Interface Module"?!?!? What's that supposed to mean? I like my version way better lol. Thanks

[codeman71]

Yeah I know...when you leave it up to engineers, that's what you get

Well that explains a lot!!! I have a 3rd gen iPod Shuffle and wondered why I didn't see an iPod on the screen like codeman71's avatar. All I see is USB. I also was wondering why I had to convert all my songs from iTunes to MP3 for it to work. Guess I need an up to date iPod. Thank goodness Christmas is coming!!! Thank you so much for this breakdown. Kinda got a blank stare at the dealer.

I was wondering why you said you had to convert your files to mp3's ON YOUR IPOD- because the older ipods act like flashdrives. Interesting. Luckily I have a 5th gen 80GB Classic, and the files were already mp3's because I initially used a flash drive. Ipod is much cooler.

Well that makes two of us!! I wondered why I had to convert too. Now I have to go shopping.

OK, so here is a question: I have a 32g iPhone 3Gs, and want to know if I hook it up via the USB port, and have the phone set to the Bluetooth in the car, while I am listening to my music files, will the bluetooth overide the music when I get an incoming call, or if I want to make an outgoing call?

My VR 2SS RS is currently being built and should be here in a few weeks...just something I was wondering.

I have another iPod that I use in my '06 Wrangler with an Alpine iPod control radio...so I would prefer to use my iPhone with the Camaro. Also, my Alpine does not let me shuffle the song library, does the system in the Camaro do a "all song" shuffle like can be done directly on the iPhone/iPod?

Not certain but I believe the iPhone will pause the music and let you pick up the call. This is more of a device thing than a Camaro thing though.

Yes, you can shuffle your library.
