received my 890 system yesterday, got it installed today. pretty straight forward install, had a hiccup trying to flash the module, had to call ADS customer service and let me tell you, the guy I dealt with was nothing short of simply awesome!!!!!! remotely connected to my computer and had me squared away in no time. as far as the install itself, it was real simple, the OBDII connections were dead easy, the Sync steering wheel wire was a bitch!!!!!! was real tight getting to it, and felt like every other wire looked blue with an orange stripe, but I found the wire and made the connection. every thing works as it should seemingly, and Im very happy with it so far. the dash kit is of great quality, and the Maestro RR was smaller than I pictured, but also good quality as were all the harnesses. Ill have some pics up tomorrow. again thanks to 2012GT/CS and Sound of Tristate
