We are in the final "inhouse" stages of beta testing the Triad2, which is initially specifically designed for the '02 Avalanche, '02 Suburban, and '02 Cadillac EXT. After successful external beta testing, the intent is to re-design (IF NECESSARY) the Triad2 to accommodate other GM vehicles. Thank you for your patience.
