In case anybody is looking, like I was, to purchase and install one of these. I have a 2005 Dodge Ram 1500 with 7 speaker Infinity system with navigation and recently purchased the CHTO-02. I was skeptical after reading some of these reviews. I only used the ACC (red), constant power (yellow), ground (black), turn on (blue/white), and RCA inputs and it sounds way better than the stock deck did and no problems. Volume goes way louder, also. My Pioneer DEH-P780MP goes to 63, I think, on the volume and I've only made it up to about 55 and it was extremely loud and still no distortion. It is as loud as the factory deck at about 40-45 and this is with the 16 band EQ flat. Always had treble all of the way up on factory deck to try to get as much out of it as possible. Much better, fuller, and louder all the way around. I set the input adjustment all of the way up, as recommended by a review that I read somewhere. The date of manufacture on the unit that I purchased was 3/08 and it did have the RCA inputs.
