i installed a z110bt in a 03 gmc denalli witha peripheral peswhips steering wheel control and the car batterey has been dying since. the charge will stay for about 4 to 5 days and then completly dead in the morning i have replaced the battery twice and the alternator. there were no problems before in installed the z110 anyone else having a problem????

Well thats certainly not normal. Sounds like an error in your install. Have it looked at.

Did you use the correct gm interface harness, or try to make it work without? Where did you get power for the steering wheel controls? If you did use an interface what brand or model is it. I know that scosche modules would kill batteries in gm trucks when they were first released due to a software issue.

i had a pac class 2 databus adapter installed i removed it thinkin it was waking up the car computer at random no diference i am a profesional installer for 20 yrs and this one has me baffled

Are you powering the unit from a constant 12v source?

That's usually the cause of this.

constant source through stock harness via AI adapter plug key source from ignition harness

Do you have the ACC wire tapped into as well?

I think your unit is staying on even when you shut off the vehicle.
