My navigation screen is completely cracked and no longer has touch screen capabilities. None of the electronics are messed up. Is there a way to replace the plastic piece instead of the entire unit ??

 

All you need is just order new LCD

thank you so much !!!! is it hard to install? or should i bring it somewhere for a mechanic to do it?

 

There are some DIYs around just search.

 

It's not that hard, just little patient and an DIY you could get it done.

 

If you don't DIY, take it to a stereo shop...not a mechanic.
