Where did you get it... I find it on ebay and the adapter on ebay also. Is there somewhere else ?
I bought EVERYTHING off eBay.... I'm sure you can find the components I used elsewhere but eBay is always easy.
Here'* a list of what I used and the price I paid before shipping:
Kenwood DPX-701 $270
Scosche GM1590B Double DIN Mounting Kit $5
PAC C2R-GM32R Databus Interface Module (if you want to keep your door chimes and RAP) $80
Scosche GM07B Ribbon Harness (if you don't care about keeping the door chimes and RAP) $5
Metra 40-VW10 Antenna Adapter $9
PAC SWI-ALP Steering Wheel Control Interface $50
There are still quite a few auctions on eBay with all of the components listed above.
I also installed the Sirius SIR-KEN1 satellite tuner at the same time. If you want to add Sirius I would recommend that you buy the tuner from a place like BestBuy or Crutchfield. From what I've found the earlier tuners had an issue with the display not showing correct channels at times or the display would only read "WAITING". I made the mistake of buying a new tuner off eBay but it was older stock and I now have this issue.
If you plan on keeping your factory Bose amp you can use the remote turn-on lead from the headunit to power up the amp. You just need to splice the turn-on wire with the PINK wire in the factory harness for the amp.
Also, if you go with the PAC SWI-ALP for the steering wheel controls, the pin # they list on the instructions for the Bonneville is wrong. The directions state the pin # is D8 on the DIM connector but it was actually A1. They also said the wire was either dark blue or light green"...
It'* dark blue.
As far as the HU install, you will need to trim some of the plastic behind in the dash but from what I understand that is pretty much "normal" when in stalling an aftermarket HU. The DPX-701 comes with a trim piece that you will need "cut to fit". Just go slow and make small cuts and you won't have any problems.
Wish I could have taken some good pics of the install but like I said my digital cam SUCKS!!!
