07 aveo radio help

[tk3445]

Hey everyone i just got my 07' Aveo and i love it however i skimped a bit and just got the AM/FM stereo figuring i could always upgrade later. well now is the time!

however i have brought my car to multiple local installation places and none of them have the "proper" wiring harness or install kits because "it is a new vechical" is what i was told. i have found the install kit, and harness on Crutchfield. however im not to sure about this stero lockout thing! and i have also heard removing the stock stero in an 07 aveo can cause other stuff not to work!

Any Light people can shed on this matter would be great

Thanks,
Tom
