I had a touchscreen Pioneer AVIC ZT 110 installed. I told them not to turn on the power until everything was installed but I think they did anyway because they called me and said the air bag warning went off, turn signals and alarm didnt' work. They decided to store the stock stereo under the passenger seat, and run the existing wires (stock amp was removed). This would allow the car to still be in contact with the stock stereo. They then installed the Pioneer stereo. All is well except the air bag warning is still on. I bought the XD Radio tuner and they installed a power antenna on the inner windshield. I think I have to get the dealership to turn off the airbag warning because all wires got reinstalled back into the stock radio

 

Hi Flip,

How do you remove the original stereo?

 

the premimum sound system is a harmon kardon system and that is a magnificent system

 

It's magnificent, but not Harman Kardon. For the earlier models the speakers were made by Volvo, and the amp (as far as i know) is from Alpine. The later models have speakers from Dynaudio. Not sure if the amp is still Alpine or something else.
