I have the normal version, is it possible to switch it to the digital one? My light is burnt out and this would be a good time to replace. Where could I find one as well?

Possible, but not easy. Everyone who has asked this question has never come back saying that they completed the swap. It involves more than just the electronic head unit.

Fix the light bulb, and carry on!

More info can be found in the search area.

Good Luck, and Welcome. Lots of great info here...

Short answer: No.

Long answer: You'd have to change out the entire HVAC ducting, run new dash/headliner wiring for all the new sensors, and then go through the heck of reprogramming the BCM for it to work. Its the one thing about the interior that just isn't possible for a DIY'er to do.

ok, well do you really have to unsolder the bulb and all? They sell em new on ebay for 80 bucks. would that be worth it? How hard is it?
