I had a place here in Steubenville, OH do the install of my D3 in my 1991 Volvo 940SE, Sirius and iPod connector. I did this because I felt that the job was a little too intense and that there would need to be some fabrication done also.
I brought it to the shop and the shop owner ended up working for my dad years ago and was pretty friendly. He said he would need to order a part to bypass the Volvo factory amps, which seemed ok with me. He charged me $240 for the install and the part. I didn't think that seemed totally outrageous considering I didn't buy any of the hardware from him.
So I drop it off Wednesday morning and he calls me mid-afternoon saying that there are a few issues, one being that the piece he ordered only bypasses the dash speakers, I wasn't quite sure at the time, but I didn't believe the dash speakers in Volvos were connected to an amp, only the 4 door speakers. He then proceeds to tell me that to get the door speakers working he needs to rewire all the doors and that it's going to cost me another $240, which included a missing cable that supposedly didn't come with my SIR-PNR2, I also felt that this wasn't true. I guess I should have put up a red flag when he said this, but I paid it, hoping that my car was going to look and sound great.
I pick it up yesterday and much to my dismay the car is a wreck! My glove box was broken, he installed a toggle switch for the parking brake, which I also believed wasn't necessary (I gave him the bypass procedure from this site) and while I'm driving video does not play unless I'm going about 10mph. I don't know if he connected the VSS wire either, in 3D calibration, it gives me a MPH reading that is within 2-3MPH of the speedometer. Worst of all, he didn't fabricate a bezel, instead he glued the bezel that came with the unit onto my dash!
I was shocked because this guy has a nice shop and I have seen some of his other work and it was good. Here are some pics:
