I own a 2007 4Runner SR5 4x4 with the stock audio/cd player system. I've been looking into installing a hands-free phone system in the vehicle and noticed that Toyota started offering a blu logic stock system for '08 and newer vehicles. I was wondering if I can install the blu logic system on my '07 4Runner or not and if it will function properly? There weren't any changes between the '07 and '08 model years that I know of. Thanks - TJ
