I use a cheap ODB2 blue tooth adapter ($25) and a phone app (Torque Pro) and connect to my Android phone (no support for "i" stuff). I can program about 8 different screens with hundreds of pre-programmed "PIDS" that show just about all the info you could ever need on my 13 F150. Boost, IAT1, IAT2, actual coolant temp, CAT temps, and on and on...
I just plug in when I want to see the gauges. Mounted a cell phone thingy, wired up a 12v charge line to it (it will suck the battery pretty fast!).
It will let calls/texts come thru while on, but if I'm towing, I don't really care so much about that! ha, ha!
Anyway, works for me and tells me a TON of info for about $30 total!
Good luck! Mitch
