ACECAR Car HUD Head Up Display, OBD+GPS Smart Gauge with Test Brake Test Overspeed Alarm HD LCD Refitting Code Table Display, Works Great for Most Cars (P6)

First the unit it works well after adjusting it in Function settings menu. Its set up for GPS mode as I drive a hybrid vehicle this is done in the Functions menu changed the Work mode from Auto which uses OBD and GPS to just GPS. I also had a problem with the unit shutting itself down after a short distance. I corrected that issue by changing the Function settings the boot mode to 2. I also changed the Boot voltage from 13.8 to 13.1. I changed the shutdown mode to 2 and the shutdown voltage from 13.2 to 12.9. It worked well all day but next day noticed the unit had changed all my settings back to their defaults I found the problem was because I didn't shut off the power on the unit and it must have depleted the internal battery to keep memory settings I had changed in the functions menu. Now that I have it all figured out I'm happy to say the unit works very well and I love it.

Bought this to augment the lack of physical gauges in my Nissan Versa. It does what it needs to but there is no setting that allows you to view the oil pressure without entering into another screen. Oil temperature is available but honestly... oil PRESSURE is much more vital. I took a star away for this because out of all the parameters I wanted to be able to monitor is Oil Pressure. Other than that it is a decent item and is really easy to install and set up.

My 99 Buick has a OBD2 port and my scanners work great with them, so naturally I wanted this OBD2 gauge for a fun gimmick. When I got this and hooked it up, it turned on but didn't show any of my cars stat. I flipped through the settings and it was already set in OBD mode. Initially I wondered why the listings say "Only cars produced after 2008" because OBD2 started in 1996 but in 2008, OBD2 adapted the ISO 15765-4 standard, so maybe this gauge relies on that specific connection to work. Its only useful as a GPS Speedometer for me but its not even worth using it as that since most smart phones can be used as GPS Speedometers.In terms of the device quality and such, it was alright. The shell felt like a kids toy and the screen can easily be pressed in, leaving potential spots. However I did like the various gauge faces, but that's the only positive I can think of.

its a nice hud just make sure you have a 05 model car and up

wasnt worth $50 to barely read speed only worked on my buddies foreign car broke a week later

Ive been using this for a few weeks and it works perfect so far. I just wish it had gas percentage built in.

The build quality seems cheap. Has limited use in pre 2008 vehicles and did not provide any useful information on a Jeep.

not working at all
