Crux SOCGM-17C Radio Replacement Interface with Chime for GM Class II Bose Amplified & Non Amplified Systems

Worked pretty good on my 2006 trailblazer with atoto head unit. Its labelled well. It also has descriptions on the wire casings as well.

Exactly what I needed for my 03 Chevy Avalanche. I don’t have steering wheel controls or on star so this was a much more affordable option. Works great with my new touch screen head unit.

funciono muy bien y muy fácil de instalar

This thing works great -- it's the second Crux box I have used in my truck, since the first one got stolen along with the radio itself (even car thieves prefer Crux, I guess). It was kind of odd that this model includes the cables to hook your steering wheel controls up to your radio, but the Crux box itself lacks the capability. I'm not sure why Crux didn't save a few bucks and exclude those cables, since they're not useful in this kit.

Been installed for 2 weeks in my 04 silverado crew cab LT with Bose premium. Works perfect to get my chimes back and for the Bose to work with after market head unit! Recommend!
