Ok so i went out to a custom audio shop to have my Alpine HU installed into my 1997 ETC with Bose. I planned on keeping the stock Bose speakers and amps i just wanted a front mounted CD player cuz in 97 there was only a cassette deck. The install was going fine then they came back and told me that the HU is tapped into the computer and due to this i would need another adapter to run and connect the stock HU in the trunk and mount the new HU in the front or else i wouldnt be able to read codes or connect my car to a computer. My car had been there for 3 hours already for what i was told was a 1 hr job so i just said forget it then. My question is while i know by removing my stock headunit ill lose my chimes and the steering wheel controlls (unless i purchase anothe adapter) or were they just tryin to squeeze me for some more cash.
