the only negative I'm hearing is that with bluestar you lose your voice commands to the navigation. Trying to find out if this is true or not.
JNUTZ didn't see a response to your question so I checked the website and Costartech.com website disclaimer at the bottom says it does disable the voice command feature.
"COSTAR Technologies and the BLUESTAR product are not affiliated with OnStar LLC or General Motors LLC. Use of the BLUESTAR product disables the OnStar equipment in the vehicle so that none of its safety and security features will function, including emergency assistance, or voice control for naviagation if equipped. It is the responsibility of the vehicle owner to advise subsequent owners of his vehicle that the OnStar system has been disabled."
