How difficult is it to change the backlight color of your dash?

 

It'll be a pain! You're better off getting a new headunit unless you have a very calm and stable hand, tiny hand tools and soldering equipment, and LOTS of patience.

 

If you wanna do the headunit just get a new deck.

If your talking about the cluster and stuff, search for LED on this site, you will find a TON of threads about LED bulb swaps. Also, keep an eye on my thread in the amplifiers section, i will be doing a cluster color swap. There are already pics of my AC controls swap.
