Review on ECOOLBUY Navigation Intelligence Computer Speeding by Jay Sterns

This little device can serve as a HUD for your old car model. If you have a manual transmission car that does not have a tachometer (1996 Honda Civics etc) and you want to know where your shifts are then this item can do the trick. If you have an older GM vehicle (pre 2000) you will need to check compatibility before purchasing. I don't actually need the GPS feature, but you need to use additional things to make it work. This item as a standalone HUD is very good. You can read all sorts of useful data from the engine computer. You may have to look up what some of the abbreviations mean, but the data is there. It gets power (12V) from your OBD port when used as a HUD. This is almost a 5 star product. It comes with mounting hardware that you can install in your car, or you can just suck it on the inside of your windshield. The included suction cup is great. I would give this product 4.5 stars for what it does.
