So I’m a little late to the conversation but here’s my two cents. I acquired my 08 in early October this year. Decided immediately I wanted to install HUD and SWC and “old” Nav unit which my base 2LT obviously didn’t arrive with from the factory.
Assembling the parts new over a period of weeks became impossible. First was a Steering Wherl from a 2011 with SWC, then I got a pristine used Nav unit from a 2011 Car in BC. Next came the gps antennae from a 2012 car in the US. Then the HUD itself from a wrecked 2012 also in the US. Got wiring from online Company in US and switch from my GM dealer. Now don’t slam me for trying to keep my car OEM and not installing a new Head. Remember it’s my monies and time to waste. It will happen eventually ! Lol
The HUD install was a bit of fun. Lots of install videos and knowledge base to draw from in various forums. And I’m happy to report it works ! And it’s quite bright ! (In my garage anyways ! Lol)
Here’s my short anology of the install. Stereo was easy. It went the theftlock immediately but I purchased a tech2 programmer and got it reprogrammed to my Vin. That was fun !
The HUD install itself was probably 6 hours for me. Took my time over a period of weeks (work, life, retirement got in the way
).
Notched the two tabs for easier install. Etc etc. the funny part was the wiring. Mixed up two wires and accidentally grounded the data stream from the Nav unit and got some very funny results. Got that fixed up and just finished putting it all back together and it appears to be functioning very well. Next I will wait for new clock spring and run the three wires to radio for SWC. I think I still have to tie in a wire from console for “time of arrival” to work but might not worry about that. It’s doubtful I will really use the NAV just wanted to keep OEM accessories. Bluetooth obviously won’t work because my Onstar VCIM is not from an 09-10 “Bluetooth” car. Those units are just silly how much wreckers want for them. Anyways… if I can do it, anyone can do it.
