Alright so I am planning on installing a kenwood double din with nav and i know that i need the harness, antenna adapter, etc. I know a lot of guys on here used the gmos lan 04 harness to hook up their double dins. I am just wondering if this harness is really necessary if you dont have onstar? I have the pioneer system but i dont have onstar so i am wondering if I should go with the expensive harness?

 

you dont need the expensive harness but you will lose all chimes (door, seatbelt, etc)

 

I assume u've got an 07+ yea?

If you have an 07+ and want door chimes/clicker of turn signal/seat belt chime: Pac C2R-GM11
If you have an 07+ and don't care for all the above mentioned: Metra 70-2202

I personally love not having door chimes and all. a couple times girls sitting shotgun accused me of not using my signal to change lanes because they didn't hear a click. LOL.

For reference, I've included the wiring guide found on a sticky to back this up. Since you are Pioneer look at the US8 connections. The other radio listed is the other mainstream mp3 deck used in 07+'s.

ok i can deal with that as long as it doesn't screw up anything else

yea its an 07, I appreciate your help warren

 

hey SJC.... just buy the expensive metra harness man. ur gonna need VSS for nav to work "right" and finding that wire is a bitch. and i work doing this **** all day. ur not going to find it and get it to work.

take my word for it

 

ok so if i buy the expensive harness is it going to save me a lot of hassle with the VSS?

 

yes, dude it will save you time and make your life so easy!

 

depends if the unit you have needs a speed sence

 

that is correct but if its a kenwood it probably does need it. I would double check thou anyway

As an FYI im actually sad theres no VSS harness option for us 05-06 guys. i might get navigation if that was the case

 

alright i appreciate everyones input. Does anyone know where i can go pick one of these up? I won't be home for a week or possibly two so i would like to try to find it somewhere so that i can attempt to get this thing installed

 

best buy or local shop should have one

 

the best buy ones wont have it, if your not going to be home order it, EBAY. be home when you get there! EBAY WILL BE THE CHEAPEST

 

picked it up for 85 at best buy

 

emp you can tap the VSS... I cant remember but for some reason I thinks its in your obd2 plug

 

ok why is my harness not matching up with my plugs from the stock radio?

 

model number of the harness?

 

x2??? spun posted a pic of the one gmos lan 04 here recently
