I just wanted to share something that I just came across while looking for a decent WIRELESS (emphasis here as I dislike cables running to OBD port) head-up display. Cost $259 (no tax + free shipping)
I came across several products that are all wired except for 1 that is in Beta stage, but is shipping now. It's called Carloudy (
http://www.carloudy.com/). Check it out. It seems like the smallest profile AND wireless intelligent head up display offered. I placed an order 10 mins ago for the shipping Android version (you'd have to pre-order the iPhone version as they're not available just yet.)
Oh btw, I'm not a affiliated with this company -- in fact I found out about it about 15 mins ago.
