DIY glass dashboard add-on

A while back I purchased a Bluetooth OBD II reader, mainly to read and clear the codes when the gas filler cap wasn't tightened enough on our cars. The one I got is the OBDLinkMX (obdlink.com).

Among other features, the Android app also includes a cool dashboard function with the ability to display multiple screens of digital or analog gauge faces of any of the OBD II data available (and there is a lot), as well as some info from whatever phone or tablet the app is running on, like acceleration. It also has a dashcam feature.

I fabbed up a mount and hook and looped to the dash, and hook and looped a 10" tablet to the mount. I set up one screen with Vehicle speed, Trip Distance, Total Fuel Economy, Fuel Rate, Volts, and Instant Fuel Economy digital gauges. We used it on last week's trip up to Lake Almanor and back and it was really nice to be able to see those things. I used the speed gauge more than the dash speedo. The gauge sizes are adjustable, and you could set up multiple screens to swipe between.



As yet unexperimented with is the "Heads Up" display function, which mirror images the screen. Presumably, you would then place the tablet on the dash such that it would be reflected by the windshield.

I also run the Bluetooth apps for the Victron battery monitor and the Renogy MPPT solar charger on the same tablet.

It worked so well that I'm considering adding at least one more 10" tablet to the dash for full-time Waze and/or Off-Line Maps and Navigation while in motion.

Nice job, I was wondering what to do with that old tablet I have hanging around.

Nice work. Great idea. I've got a '02 so my system is a J1587. Have to use this adapter from Amazon: OBD II to J1587/J1939

My OBD II reader may or may not be able to read J1587, I'll find out soon as I get the cable adapter. It's kinda cool because it Blue Tooth connects to my phone. Didn't cost much as I recall.

I was given a new android tablet not long ago for sitting through a time share presentation (didn't purchase, $9,000 buy in...yikes!) and was wondering what I'll do with it.

Thanks for the idea!

I was just reading the Ford F-53 Owners Manual and saw this note. I suspect it's the normal warranty disclaimer verbiage but I was surprised to see that they are specifically disclaiming insurance company monitoring devices. Obviously Ford has no way to control power drain etc. of third-party devices so I wonder if the insurance companies let their customers know about this possibility. Bold emphasis is mine.

On Board Diagnostics Data Link Connector

WARNING: Do not connect wireless plug-in devices to the data link connector. Unauthorized third parties could gain access to vehicle data and impair the performance of safety related systems. Only allow repair facilities that follow our service and repair instructions to connect their equipment to the data link connector.

Your vehicle has an OBD Data Link Connector (DLC) that is used in conjunction with a diagnostic scan tool for vehicle diagnostics, repairs and reprogramming services.

Installing an aftermarket device that uses the DLC during normal driving for purposes such as remote insurance company monitoring, transmission of vehicle data to other devices or entities, or altering the performance of the vehicle, may cause interference with or even damage to vehicle systems. We do not recommend or endorse the use of aftermarket plug-in devices unless approved by Ford. The vehicle Warranty will not cover damage caused by an aftermarket plug-in device.

Just one of the many reasons that I use a 20-year old flip-phone.
