well,my wife and i were wondering if when you lock your doors w/ the key fob,is it supposed to honk the horn,like on my silverado and her old trailbalzer when you pressed it twice,it would honk,and the h3 doesnt do it,if so,is there any reason why it if there is a way to do it,i would like to know,its just one of those things when you are walking away just to hear it lock,let me know

 

also would like to know how to take the factory stereo out

 

Hello about the horn lock to set it to that setting just look in owners manual it will tell you what you need to know alot of us do not read the owners manual.Thanks and have a good day

 

so it can actually be done,right on

 

Yeah, I am not sure why it isn't default switched on on the H3 as it is with every other GM car.
