gm lan system????
i heard when u take out the factory head unit you will not be able to use the computer to check the codes in the car? Is this true, has anyone checked for codes while having a aftermarket headunit? Also has anyone got a inspection yet with there aftermarket headunit installed?

Cobalts do not use the GM LAN system. If you take out the head unit you still have the door chime- turn signal tick- ect. As long as the aftermarket unit is installed right it shouldn't affect the codes.
That being said it is still safer to leave stock headunits alone and upgrade the rest of you system... weird stuff happens sometimes- i just saw a post on here form a guy who's cruise control doesn't work with the aftermarket head unit.
If you want thump just add an amp and a couple 12" subs,
If you want quality in your music go with some 2 amps, 3 or 4 cone speakers all around, and 1 or 2 high power 10" subs. Thats what I have in my SS with the stock head unit and it sounds awsome!

If something doesnt work after you install a head unit, then most likly it is the fault of the installer who probly cut a random wire somewhere. I install my head unit and lost nothing everything works fine.

i know its a weird question but if you got your car inspected with the aftermarket headunit then that means the computer is working just fine.. So has anyone gotten there cars inspected yet with the aftermarket hu?

the only reason certain things may stop working is because somebody blew a fuse somewhere, while installing my flip up tv head unit i flew a few (15A i think) and it powered the radio and keyless entry remote(which both stopped working when the fuse blew). just random things are tapped into the same fuse....now this is on a cobalt ss/sc, fuse configurations may vary amoung cobalt models...

Oh hell no. I don't even deal with people who try to tell me something completely bogus. It just pisses me off when they are "right" and they know nothing. It's just how it is. Trsut me, you'd like to be a customer of this shop if you were in the area. Lol.

Your car will pass NY inspection since any code set by the computer is not a trouble code. If a GM Tech plugs into it they will likely see an alert that says something to the effect of radio communication lost, but that shouldn't be anything that will make you fail an inspection.

okay street dreams my bad i quoted the post that you quoted the other guy and i thought the whole comment would show up. it was intended for the guy who is an "installer" who said 2 or 3 amps and some nice cone speakers would sound good sorry for the confusion fyi all speakers have a cone except for some tweeter that have a dome over the voice coil to project the sound
