A lifetime ago I was looking at the motec system for my Eclipse GSX. If I still had the car I would totally do it!Yeah, not cheap, but it's a Motec device. The display itself is typically $2k. Throw in the development costs, the mount, the CAN bus adapter, and the fact you can basically configure the screen to your heart's desire, it's quite a fair price. The value is there if you're into motorsports. If not, then yes, it's just expensive.
The EVTV adapter EVTV Motor Verks Store: Tesla Model 3 OBDII Adapter, OEM Electric Vehicle Items, Model3OBDII2019 plus Torque app can do this. Torque has a HUD mode for its gauge displays. I have an 8 inch tablet mounted on my dash, so I can do direct view or tilt it to reflect off windshield for a HUD.
