Sorry everyone, I spent the last 2 weeks packing up & moving to a new place. I have the gauge hump & will get online today & get a HUD unit. I need to unpack all my tools & get a little organized. My goal is to start this project in the next 2-3 weeks. I'll post pics & updates as soon as i get going.

Note that HUDs connect in two manners: 1. To OBDII port or 2. to cigarette lighter port.
The cigarette lighter models can be hard wired, but it has to be to a separate female cigarette socket (available at Radio Shack) that itself is hard wired to 12 vt supply. You cannot just cut the wire from the HUD and splice to a 12Vt power source because the voltage in the HUD is not 12 VT. It is much less, like maybe 5 vt. the provided male socket reduces the voltage from 12 vt. Thus you must somehow retain the male socket.
I tried a couple of these. They had short lives, failing in weeks. Both were made by no-name mfgs in Taiwan and sold through Amazon. They are cheap, and not worth your money and time.

A couple of years ago I tried aftermarket HUDs as sold through Amazon. There appears to be two basic technologies used to read speed: 1. a wired connection through the OBDII port; and 2. a GPS speed reader.
I bought both examples. They were cheap. Some of these units are sold through apparent USA corporations. The units I bought were made in Taiwan, maybe by the same manufacturer.
Installation was comparatively easy, but I was not dazzled with the performance. Image faded in bright sun, even with the reflective patch on the windshield. I removed them after about three weeks.
I don't think really good HUDs are available cheaply. HUD is not a cheap oem option - like $900 extra on a Mercedes S Class. Tesla, perhaps a leader in information technology, does not offer HUD.

I had no luck
I was the guy trying to fit one of those & the problem is the angle of the hump piece on our dash. The only way to make this look even close to a factory setup throws the projection way to high up on the windshield. It just winds up being distracting. The corvettes I had all projected down beneath your site line & that’s the ideal location. The only way I could see this project being successful is if someone custom molded a new hump piece & has it wrapped in leather & you try to keep somewhat of a stock look.
