All 00+ Bonnevilles use the lock & dock connector and have data-bus controlled radios and amplifiers if equiped with premium sound(both Bose and Monsoon varients). SRS deployment is not affected by removal of OEM head unit. Chimes, audible warnings for check/service lights, and OnStar functionality are the only items lost, as previously stated. A system unhealthy responce will likely be generated if a Tech2/3 is connected to the car sans factory radio, but will not negatively effect other databus controled system. The only parts Best Buy has for the 00+ Bonneville is the dashkit, VW ant adapter and Scosche GM07 harness (non-data integration). I haven't check in the last month or so, but there is a possibility the Scosche part DCGM14B (its actually designed by Perepheral Electronics) could be special ordered, but oddly enough Scosche only lists 01-03 model years for Bonneville for some reason. Probably an error on their part. This part will not retain OnStar, only create RAP lead and chimes. I agree whole heartedly on using databus interfaces if possible, but I've done several Bonneviilles/Le Sabres without with no negative effects other than me having to spend more time completing the install. ...and remote start installs are very straight forward, nothing special with the ignition harness other than the fact it is low current wiring.

Ya just to confirm, I checked Mitchell and confirmed that the SIR system is tied into the radio with Class 2 as there seems to be alot of confusion surrounding this both in the industry and with consumers.

You will probably have to buy a antenna adapter from Mini to Standard size as GM likes to use the mini antenna plug for some reason.

If you want to retain steering wheel controls there is a module available through BestBuy (Talk to the Installers).

Its only money you can't take it with you

You could buy the modules first and sit on them until you have the money for the deck that you want. Just a thought.

JVC has some nice decks without breaking the bank, shop around including online.

Dutch, that is incorrect. I have had my car connected to a TECH II scanner at a GM dealership without my factory radio installed and my car showed no error codes. There certaintly weren't any pertaining to the air bag system. If there is ANY problem with the airbag system, you'd get a warning of some kind, not just the light flashing a certain number of times when you start the car. I have an FSM as well and it has NO mention of using the flashing airbag light for any diagnosis of any kind.

I recently started working for Best Buy after working in the industry for years with other business'
I don't know what stock Best Buy in the States has but we have alot of different modules up here in Canada.

BlackIce as far as what you and others have stated, I would not trust my life or a customers, to the fact that we would hope that the Air Bag System will be uneffected by disconnecting the factory radio without the proper interface.
The only persons word I would trust on this matter would be a GM electronic engineer who designed this system. This is why Best Buy and many retailers will not do the install unless the customer buys the necessary parts.

Like I said I double checked Mitchell On Demand and it says the SIR (Supplemental Inflateable Restraint System) is tied into the Radio Data Bus System. FYI Mitchell is the same program that the Dealerships use for Wiring, repairs, etc.

Anyone want to unplug there radio, be a crash test dummy and post the results ?

here is an auction listing for a databus harness...

You will also need the GM double-DIN dashkit, Metra, Scosche and American International all make one, and a VW antenna adapter, not a GM adapter....Metra part 40-VW10

For Steering wheel controls...you can use the Perepherial SWI-X or Scosche SWC-1 (same part, different sticker) with any head unit that comes with a wireless infra-red remote control...or purchase a specific adapter based upon radio brand if the radio has a hard-wired remote control input on the back of it. Looks like a mini-jack/headphone connector, usually light blue or black in color.

edit for ant adapter...

I don't think GM would be so stupid as to put such a vital function into something like a RADIO, especially with how often they're stolen. Can you say lawsuit waiting to happen? No offense, but I've had Best Buy work on my vehicles before and they've always managed to screw it up one way or another, including disconnecting the parking brake switch so that the warning never comes up because they screwed up the brake sensor, or other random warnings after an *attempted* remote starter installation. I've seen the information they have on their computers first hand, and I am not one to trust it. Again, if the airbag system weren't to work correctly there undoubtedly WOULD be a DTC set of some kind. I've had my car scanned several times for various reasons and there have never been any errors of any kind after the stock headunit removal.

Here is the Proof:

Check out the Top Left of the wiring Diagram. This is the wiring Schematic for the Radio.

Sorry about your bad experiences with Best Buy.
There are butchers & rookies in every trade including mine.
The difference between me and them is that I care and I'm a licensed veteran

These are the GM schematics for the SIR system, for both the modules, and sensors. The head unit is not shown in either schematic. I also looked in the service manual for diagnosing problems with the SIR system.
here is step one:
1. Test to see if the AIR BAG indicator flashes seven times when the ignition is turned ON. The AIR BAG indicator should turn OFF after flashing 7 times. If the AIR BAG indicator turns off after seven flashes, the SDM has completed its self test successfully.




This is a complete list of all SIR components. (divided into sections of the vehicle)
(1) Brake Fluid Level Switch
(2) Cruise Control Module (CCM)
(3) G106
(4) Inflatable Restraint Front End Sensor
(5) C101
(6) P100
(7) C112
(1) Traction Control Switch (Column Shift w/NW9)
(2) Gear Shift Lever
(3) Steering Wheel
(4) Inflatable Restraint Steering Wheel Module
(5) Horn Switch Contact
(6) Inflatable Restraint Steering Wheel Module Connector
(7) Inflatable Restraint Steering Wheel Module Coil
(1) Inflatable Restraint IP Inflator Module
(2) Inflatable Restraint IP Module Connector and Wiring Harness
(3) Instrument Panel
(1) Inflatable Restraint Sensing and Diagnostic Module (SDM)
(2) Inflatable Restraint Sensing and Diagnostic Module Connector and Wiring Harness
(1) Inflatable Restraint Side Impact Sensor (SIS) -- Driver (Passenger Similar)
(2) Center Pillar
(3) Inflatable Restraint Side Impact Sensor Connector and Wiring Harness -- Driver (Passenger Similar)
(1) Driver Seat (Passenger Similar)
(2) Driver Inflatable Restraint Side Impact Inflator Module (Passenger Similar)

This is a good discussion. I tried viewing your schematic you posted, but it'* too blurry to read.

Custom88 do you have the Radio Diagram from the FSM ?

If so please post it as I would like to take a look at it.

Everything you mentioned about the diagnostic checks on the SIR system I already read in Mitchell.
The wiring diagrams you posted are only 1 part of the Data Bus system.

When I mentioned before about the number of SIR light flashs I think I mixed it up with the first Gen Data Bus which was Caviler, Sunfire, Monte Carlo etc.

The Class 2 Data system if the light stays on after 7 flashes its screwy and there is another, situtation in which it means touble.

Please post the radio from FSM & I will try and blow up the one I posted

Dutch

if there is a problem the light will stay ON, the light blinks while OBD is being performed and when the system passes OBD, then the light shuts off

dont make me deploy my airbags just to prove you wrong

unfortunately, you have no proof of your claims, we have service manuals and HANDS ON experience with the databuss systems in THESE CARS you need to prove it to us, we dont have to prove it to you
