AUTOOL X70 Multi-Function OBD Hud Speedometer Automotive Head Up Display Smart Meter & Alarm Fault Code Water Temperature Gauge Digital Voltage Support 12V OBDII J1850 Diesel Gasoline Cars

The temp meter on my van died which to replace was going to be hundreds of dollars. This simple plug in is great! It gives more than hot/cold but the real temperature. And you can set an alarm at whatever temperature makes sense for your vehicle. You towing something and don't want to overheat? Cheap way to really know how hot things are getting. BTW, company very quick to respond. Very impressed

The description on this says it has a boost gauge. This is the entire reason I bought it. It does NOT. This item only has one mode - it shows speed, RPM, voltage, and temp all on one screen. That can’t be changed. I am returning this for in accurate description.

Not sure what this is supposed to connect to, but it came without a cable to connect to ODB ports, it does come with a power cable and a telephone cable however. Took 2 months to get it delivered too, I should’ve bought a different product, returned this immediately.

the first car you install well work but you cannot use it for any other cars
