VJOYCAR Car Universal HUD Head Up Display, OBD2 GPS Dual System, Vehicle Speed MPH KM/H, Engine RPM, Overspeed Warning, Mileage Odometer, Coolant, Voltage

I bought this for my 2007 Jaguar XK. Two things that are very sensitive on these cars are: A) electronics needing optimal voltage and B) engine temperature given many plastic parts of cooling system including water pump impeller. Two things that the car gives you no info about? Voltage and Coolant temperature. This just plugged into the OBD part under and left of the steering wheel column and I was able to cleanly route it and mount it in front of speedometer which isn't needed because the readout screen I use has speed, ECT (engine coolant temperature), and battery voltage. It gives me huge peace of mind for little cost and little effort to install in a clean way. The one change I had to make was to make Temperature go from Celsius to Fahrenheit. I had to read the included instructions. You have to be plugged into the car to do this. I tried using the USB at my computer in the house but couldn't get to the menu to do set up I needed that way. No big deal. I was also pleased that it turns on and off automatically as the car is started and then about 10 seconds after you shut car down. The temperature readout recorded the same as my OBD reader and the speedometer was right on the mark with my dashboard readout. If some readings are off a bit I believe I saw in the menu where you can manually calibrate them. I love the tool and recommend it for anyone who wants numeric readouts, not a light that comes AFTER a problem has occurred.

Easy plug & play. Included 1 OBD II cable and 1 USB cable, connect to OBD II port on vehicles newer than 1996 , or use the USB (no cig adapter included). It immediately started displaying information. Works great on OBD and GPS in my 2004 VW Passat diesel. Minus 1 star because it doesn't work for my 2005 Chev Suburban .Speedometer accuracy is good and can be adjusted easily. The GPS info was also accurate for my location and travel direction. I would buy it again

I had bought this unit to help my 76 year old mother to drive my 2004 Ford Ranger. It did not work in OBD mode, but it did work in GPS mode (was pretty accurate, only 1mph faster than actual speed). I also tried it on my 2011 Ford F-150, the OBD mode did work so the unit works as advertised. I have to admit it is kind of cool having a digital speedometer for all of 5 minutes. Then again I did buy it for her and not me. As far as helping her see the speedometer, it helped. Unfortunately I think she needs a stronger prescription for her glasses.

Does not work for my Subaru Legacy. The sole purpose as to why I purchased this was a need of a gauge for monitoring my coolant temperature, and oil temperature. This does none of it. I don't know why. All it does is battery volt, driving distance, GPS, ASL, (have no clue what that is). Other than battery voltage I like the other stuff is useless. Gotta return this back.

I have a 2005 GMC Sierra Denali and this thing doesn’t pick up the obd2 that’s the only thing I bought this thing for and it’s incompatible with my truck but the team with product will really help you out I really appreciate them helping me fix the issue and everything works as described the gps works and is very accurate with the vehicle

I've been using this product for a few weeks now, and it works well. Sadly, it only works in GPS mode in my 2008 VW Golf GTI Mk 5, as it says the OBD2 interface is incompatible. So I am using it in GPS mode and just use the OBD2 connector for power. It picks up the GPS signal quickly, and responds quickly to changes in speed. It's more responsive than my GPS unit in this respect. The display is clear and bright and easily read in daylight. Haven't tried it at night yet. It was easy to connect, and using the menus is straightforward. I had no trouble adjusting the displayed speed to match that of my GPS unit. It does exactly what I wanted.

Works for only 1 of my cars and now it dont work only 2 months and stop working, cheap product only works until the product warranty is up

Pretty cool device, works on 2006 police intercepter, gave the exact same problem codes as Orileys. Speedometer works very well, my cluster still works and it matches MPH very close. Great for anyone that likes to do their own auto work.

Déçu par la qualitée des informations. Les températures gelent, ne bougent pas. Aucune utilité si ça fonctionne mal.
