Default HEAD UNIT replacement (RIPOFF?)

I know some of you ahve replaced the factory stereo, but has anyone considered keeping the stock speakers/amps and swapping out JUST the head unit? I am in the process of doing this and have an appointment on Thursday to get the Eclipse AVX2494 installed. Now, the shop is charging me $100 to install and $350 for parts and a custom trim piece so it looks factory. This seems high to me and I wanted to get opinions. Finally, for those who have done this, what wiring harness did you use? I cant find anything anywhere that will work, although rumor has it the Bose in our C6 uses the same adaptors as in the H2 Hummer. Any truth to this?

Default OEM stereo is ok with me

Don't want any problems with codes since PCM or BCM must recognize code from stereo.

Sure the stock unit works fine but I am replacing it with a double din unit from Eclipse that plays dvds and has a 20 Gig hard drive built in that records your cds onto it and it acts like one huge juke box. No more cds laying around and it also has the capability of navigation.

Replacing the speakers is one thing but replacing the head unit seems like you'd be opening up a can of worms. with so much tied into that ....youre a braver man than i am.

I remember sometime back wanting to replace some components of a Bose system on a C5 but the ohm rating was not standard and I was told I would essentailly have to start from scratch. Is this still true????

Apparently with the C6, it is easy to replace the front and rear speakers with aftermarket (with the exception of the 10's in the doors), Your right on the C5's, most people went with a new Stereo head and speaks....

You better do some serious research before you do a swap. Based on the above response, you dont appear to know too much about how your car operates. I wouldnt trust the stereo shop either unless they have worked on the C6 before and are aware of the electronics involved. Good luck!

Wow, Bose really has a hold of you once you have their system. You either have to rewire the whole car to bypass the factory amps or just repalce everything. What a pain. I wish a 1SX or 1SA was available when I bought (although I wouldve missed the HUD).

I would be careful with a shop that says it can work on the C6 no matter what the price is. I talked to a supposedly top stereo shop about changing a couple of things. I was left with the impression they were not that savy. I was afraid I would have a mess after they finished. The C6 is too new. Not too many people know what they are doing with it yet.

I was hoping that our C6's Bose was similar to another system GM uses in another car so that I have some basis to start with. Well, I 'll be the guinea pig folks!

Looks like others have already dropped a new head unit in. Here is a quote I lifted from another site where someone else has pulled his OEM radio and stuck in an aftermarket NAV system.

Okay it is in. i just got home and my eclispe avn 2454 is in and working. the wiring harness from the c5 works along with a bose interface unit. everything is working fine and it sounds great. now to go out and unplug the wire to the parking brake so when listening to live concert dvds the picture will be on the screen instead of cutting out. just one more toy in the coolest car on the road. now i got to get my jl audio speakers in!!!!

Here is a link to a picture of his install.

You apparently misunderstood the intent of my post, I was sincere in making sure you didnt open up a can of worms. Best of luck with your stereo swap.

One of the problems with switching radio heads on a C6 (same as with a C5) is that the power to the radio is supplied by the BCM (Body Control Module). On most other radio systems, power to the radio head is supplied directly from a fused circuit.
Also, the radio head on a C6 (as well as the C5) is part of the Serial Data comm link that connects all the major components of the car to each other. For these reasons, the Vette (and some other GM vehicles) require special jumper wire harness for power. In addition, due to the Bose setup, they also require special harnesses for speaker hookup.

Now, for your other question on what PCM/BCM is, the following will describe the two different internal communication systems used on the Vette, and the controllers connected in both systems.
The Corvette has two different internal communication systems; on is called the GMLAN and is a high-speed system that allows the following computers to communicated:
BCM (body control module)
OnStar module (communication interface module)
ESC (electronic suspension control) module
TCM (transmission control module)
EBCM (electronic brake control module)
ECM (engine control module)

The other is a class 2 comm link connects the following components:
DDM (driver door module)
DDS (driver door switch)
DPM (driver position module)
HUD (head up display)
IPC (instrument panel cluster)
SDM (sensing and diagnostic module)
SCLCM (steering column lock control module)
BCM
OnStar Module
DRR (digital radio receiver) (aka XM Radio)
FTC (folding top controller)
HVAC control module
PDM (passenger door module)
Radio
RCDLR (remote control lock door receiver)

There is no PCM on the C6; as there was on the C5. Technically speaking a PCM is a powertrain control module, and includes the programming for the engine and transmission inside one separate module. However, on the C6, there are two separate modules; an ECM (engine control module) and a TCM (transmission control module - auto only.)

A note to finish off this message. For those who leave their cars sit a long time between running without a battery tender, remember, the majority (maybe all) of these modules draw current, even when the vehicle is turned off.

Now, you have probably learned more than you asked for, and I need a life.
