Nice to monitor your engine vitals

Accurate and reliable!
I installed this Edge monitor on my 2007 Silverado 2500hd classic with the duramax diesel, and it is excellent! Following the directions, I updated it by bringing it inside and powering it with USB, and connecting to my wifi. The update took about 15 minutes. Afterwards, connecting it to the truck was super easy (it actually took more time orienting the suction cup mount to a satisfactory position). The display can be changed to your liking to show the a set of common values (rpm, speed, coolant temp), or even custom PIDs you want to see (rail pressure, trans temp, fuel level, etc). The display is responsive and clear, easy to read even in bright sunlight. It also goes to sleep when you turn the truck off and wakes by itself when cranking to save your battery! The only issue i've ever had was the screen went to sleep by itself once during a long drive as if the OBD port has stopped delivering power, but just touching the screen woke it again. I suspect the issue is with my truck and not the edge unit.

Awesome product
I never write a report but this product is awesome. Plug and play. My speedometer quit working and a gauge cluster was 400. This thing has a Speedo. Gives you error codes different gauge set-up worth the money

Perfect for my truck
Works perfectly, although it stays on sometimes which doesn't make sense.

Great monitor!
This is a great monitor. It took me a while to choose between this and the tuner version. I later learned that with this monitor you can choose to upgrade it to a tuner on the Edge website. You just buy and download the software update and download the tunes to it! That would have saved me a couple weeks of flip flopping on my decision. I have noticed it does freeze up on me occasionally but not very often at all. I would say only two times at the most in the 6 months I have owned it. The layout looks really good and gives me all the info I need at a glance. I have compared the readings with my scan tool and everything seems to be reporting accurately. It is very intuitive and easy to use. It is a bit expensive but the quality is worth the price for me! Highly recommend!

Does not work with Toyota 4Runner!!!
Does not work on a 2019 Toyota 4Runner. Tried everything to get it to work, reached out to the Manufactur and was told none of their products work on Toyotas. Very disappointed.
