Thread: HUD/DIC relationship question

I got my '04 GP reassembled and the HUD works wonderfully, but as the 5-button DIC isn't back from getting its miles matched (ETA Wednesday), when I was doing my adjustments, I noticed a few things:

One thing is the HUD isn't switching to Format 1; just between Formats 2 & 3. Now, I KNOW the compass and ambient air temp gauge work; I'd tested the DIC earlier. But right now those two features aren't booting up on screen; turn signals, radio channel (though that goes away after a few seconds) and high beams work perfectly! And gear position (also a DIC function) isn't on screen. And I don't have key in ignition or headlamps on chimes...

Which leads me to the question: does the current absence of the DIC limit what the HUD is projecting? Seems logical, but I wanted your opinions first...

I got it used (GM no longer sell new... unless they're hoarding NOS parts) from an '05 GT, and I sent it to AJR International in Highland Park, IL. I'll see it either late this afternoon or tomorrow...

No problem; whoever told you DICs can't be reprogrammed just doesn't have the facts, because it was no problem for AJR! And they charged only $80 plus tax, which is a sight better than a visit to the garage! Even adding the $24 shipping both ways is still better than a visit to the garage...

Got my DIC back, plugged it in... RESULT! ...Though I think the photosensor may have developed a fault; it would not switch the lights off, though that was on the return trip from filling up and getting the left front tyre patched... (when I left the HUD's brightness auto-adjust worked instantly)

And the miles popped up completely accurately!

Yep! But they send it back when they're done. Still, expect to have the car sidelined for a week, week and a half, depending on how quickly the posts reach them (since I live intrastate and < 200 miles from them, it moved rather swiftly).
