This HUD works pretty well. I tried it on several vehicles and had varying levels of success getting it to work. It worked great on the ones that were newer than 2004 like the description says, but not so much on older vehicles (2002). So make sure you are buying this for a 2004+ vehicle. At first I just plugged in the device and had it reflecting on the windshield without the reflector that came in the box. This worked but there was a distinct double image that happened. Once I applied the reflector panel, the double image went away and the brightness of the display increased quite a bit.
