So I looked at the cts2 and a few other old displays. I was shocked at some of the prices! Anywhere from $1000 down to a few hundred.
Maybe I'm being cheap here but I think even the low end was outrageous. So I started looking at the apps for obd2 for my iPhone. Some of them look pretty good. Problem is I don't want my phone tied up as a gauge while I'm driving. Luckily I found a very cheap $50 tablet at Wallmart today. It operates on Android 4.4 (same as Galaxy) and is about the same size as a cts2.
I also ordered a cheap obd2 blue tooth transmitter for about $8 shipped. Once it gets here I'll download a free app just to see how it works. If it works good. I look into a nicer app to purchase.
I'll post some pics and thoughts once the transmitter gets here.
