I purchased an mm3 tuner from a company a couple of weeks back.

I installed their tunes and didn't like them, so went to a reputable tuner instead?

Install their tunes and have a blank screen on my radio, and remote start doesn't work.

My question is on the module that connects the USB. Is it suppose to be 2 pieces that connect, or did they come out with a new style that is just one big long module now?
