Product does not work in my 2004 freestar only said hud. Works in an 2010 Yukon though bad system didn't buy it for the Yukon 
 Ok 
 can't see it. 
 No instructions in box on how to install. Product looks like it should be in a bag but it isn't plus rhrrrrrewq 
 Through codes in my car made my abs turn off. Very unregulated that is dangerous.. they also tried bribing me to take this down. 
 The display started to fail - began to flicker bright and dim - about a week after we received it and after only about 3 hours usage. Stopped flickering for a few days - so I didn't return it - then started again but this time all the display except the rpm indicator would go off completely then bright then dim. Tried it on a different car in case it was the car but same flickering. Pity because when working it was quite good. Now too late to return so money down the drain! 
 This doesn't work in a 2004 Chevy Blazer. 
 I cannot get it to work.not happy 
 This thing is full of problems that should have been resolved before the item shipped out.  Installation was easy but programming the unit wasn't.  One switch and one dial handle multiple functions. That never works out well but is very common on Chinese electronics. It made the setup programming much more difficult.  It also makes it impossible to make a quick change without having to unattach the unit from the dash and fumble with it for five minutes.  The speed indicator can be programmed to show Miles Per Hour rather than Kilometers Per Hour, but the conversion to the American system of measurement is only available for speed and temperature readings.  The reading for how much gasoline is being used remains in liters rather than gallons.  The written programming instructions are inadequate.  I was able to figure out how to program it because of the kind souls that posted youtube videos showing us how.

The viewing screen that mounts on the windshield to get rid of the double image is very noticeable from outside the car.  It appears as a silver square that looks like it's blocking the line of sight for the driver.  When I shut the engine off, the HUD turns off after a few seconds. However, when I later start the car again, the HUD unit does not turn on. Instructions say it will turn on after 30 to 60 seconds but I've found that even five minutes later the unit remains dark. I'm required to reach over the dash and use a flip switch every time I start the engine. It's not unusual for the unit to 'lock up' with the mph and other readings frozen.  The refresh rate for the mph reading is about once every three seconds which is much too slow. 
 Did not work from the start.
