NEED HELP ASAP WITH EDGE SCAN GAUGE

so I got the edge unit the new one insight cs scan gauge ..... GIANT PIECE OF SHIT!!!! Looks good, great concept with the ability to have 8 gauges going @ once, small and compact and full color if you'd like. unfortunately, the FIRST one I got worked for roughly 2 hours then burned itself out and died. Called edge, they apologized and stated that this was very odd. Sent replacement unit overnight no questions asked. Great cust. service. Got second one, worked for 20 minutes, turned my traction control light on, flickered a couple of times, rpm needle jumping around, and won't read any signals. Now i get to send both units back and try and get full refund to auto anything. Any ideas why this turd won't work with my truck? 2011 taco. I'm wondering if i should just get a scan gauge instead. any thoughts?

Do you have an Android phone or tablet? If so, I recommend the Torque app with a bluetooth OBD adapter. I am very happy with mine. I can post up pics if you want.
