I have a terrific 2015 Corvette stingray ....since I bought it used with a little more than 7000 miles on it there were a few features that did not come with the car...... it is a 1LT interior so it does not have the HUD display..... if I purchased a GM display it would cost six to $700.... I also see aftermarket HUD displays for about $50..... these displays plug into the OBD2 port..... One such brand is Quiita A8.... has anybody out there tried these displays.... are they any good? Thanks for responding and your feedback !
The consensus here over the years is it's extremely complicated and expensive to retrofit the OEM unit. Aftermarket is the way to go. I haven't seen many aftermarket reviews in this forum.
I had an OBD HUD added to my 2011 Camaro back in the day, it wasn't great, had a 1 second delayed response for speed and reflected poorly since the glass wasn't the right type. If you go aftermarket don't get the cheapest thing on ebay, and at least get one with its own pop up glass to reflect upon.
That being said, every vehicle I buy now has an integrated HUD, even my Mazda, as the OEM units are truly the best way to go.

As Bob said the windshields are different. To properly see the HUD projection the materials in the windshield, probably the plastic safety film, are different.

what about those with tinted windshield!!!
i know the support and under the windshield the whole assembly is different, but the windshield that’s a first.
Jerry is correct, the intelayer on a HUD windshield is different . The interlayer corrects for refractive differences because of the bend in the glass where the image is projected . This would lead to double images or a fuzzy image . It has nothing to do with image brightness or any of the other hocus pocus you read about

A C6 did not need a HUD windshield because where the image is projected was a very flat area and did not produce any image issues

Well, GM went to the trouble and expense of using a specific HUD windshield on the C6 (and C5). They could have saved money and complication by using just the standard w/s, but chose not to. People who installed a factory HUD in C6's with the standard w/s reported varying results- some said it looked identical to their buddy's factory setup, others said it was noticeably worse. It would be nice to find the GM HUD in a C7 with regular w/s and do a side-by-side comparison in different lighting conditions.
Modifying cars, even with factory parts, gets harder with every generation.
Jim , I have been in the manufacturing , distribution and installation for over 35 years . I am not going to debate with you the merits of using an HUD interlayer , yes GM did do it but was it needed .... I can tell you with a 100 % certainty that if I put the two C6 windshields side by side , I would bet u $1,000 that you would not be able to tell the difference in image quaility or tell me which one was the HUD .
Remember these folks that are saying there was a difference are the same folks that report they feel. HP gain with a cat back exhaust lol
As far as doing a side by side in a C7, stay tuned as I need a windshield in my C7 as I have a stone mark that is just above my line of vision, so far it has not bothered me bad enough to replace just yet but.....
I will have both AGC branded windshields on hand and we will do a dry set against an image board and see if we can detect any banding or distortion
my guess is there will be distortion because of where the image projects on the glass , I am confident that there will be the need for image correction
Bob... would you please explain your thoughts more fully to me about the need to change the windshield.....
The windshield for the HUD is different from the non-HUD windshield it has to do with the HUD needing to be able to reflect on the windshield. Take a look at the windshield of any C7 with HUD and you'll see the Factory Marking in the corner of the windshield says HUD. Using a non-HUD windshield you won't get the reflection that you need to be able to see it.
If you're unhappy with the Corvette, trade up to one you are happy with. I'd never own a 1LT Corvette, much less one without HUD. That said, life does go on without HUD. Although I use it continuously while driving my 3LT C7.
With all the distracted drivers I find HUD a necessity! Use it in the Vette and wife's SUV. Would not buy a car without it. Although I had a 3LT 2014 Z51 a 2LT Grand Sport was all I purchased since GM got cheap on the 3LT interiors starting in 2016! Loved my 3LT Kalahari but not the reduced color dash and door panels available now accept for Spice Red.
HUD:
. Another discovery I made with my 3LT: It has a mode for Speed Limit & current speed on your C7. Based on GPS, of course. You're going to need to have NAV on your C7 for this. The gear you're in on the M7, is ALSO included in the Speed Limit mode.
The prevailing Speed Limit indicator will let you know to keep your speed in mind to avoid speeding tickets.No need to look for speed limit signs.
BTW: I absolutely love my NAV! Just used it yesterday navigating to and from the ******* Texan Resort in Grapevine, TX., located several miles North of the somewhat rural Dallas-Fort Worth Regional airport.
As others have said, while it is POSSIBLE to retrofit a HUD to a C7 1LT, the expense and trouble make it very unappetizing.
The C6 was easy, and could be performed via the "cut the duct" method in an hour or two. ( I did the C6 HUD upgrade twice myself -- the last time on my 2012 GS -- no problem)
The C7 -- well, there is a write-up on this very board detailing the process. I can tell you -- I've been wrenching for decades, but when I read that write-up, I gave it a big fat NOPE. Not worth the hackery, and decided then and there my C7 would have FACTORY HUD or no HUD at all.
Godspeed to you if you attempt it.
