I want to replace my instrument/speedometer glass/plastic. Is this difficult to do or must I bring to a dealer. Any help appreciated.

 

It's probably not that difficult once you remove the instrument cluster from the dash. I've never touched it on my 06 Sonata but I did remove the instrument cluster on my 2000 Tiburon for the purpose of changing the gauge faces. Once removed the plastic lens was easy to separate from the cluster.

The best thing to do would be to do as much research as you can to get info for your specific year and how the cluster comes out and see if you are comfortable doing it yourself. If so, give it a shot.
