My 08 350 nav screen is acting up and partial screen is frozen not allowing me to press any options. All the other electricals function properly so this leads me to believe it is the digitizer that is faulty. I remember this was an issue with some cars especially the IS's, some have repaired them with cinductive pens, and some have replaced the digitizer with a new one off ebay. Im planning on just replacing the digitizer, since theres so many options on ebay with some costing from $20-$250. My question is if you have replaced your digitizer with success which brand did you use and how was the picture quality?

 

This should cover it

Purchased the new screen from seller CARBONDNA on ebay and works perfectly for 50 bucks! He is also a member here too! Quick install!! Couldn't be happier and saved a TON of money! If you have a touchscreen not responding, as I did, this fixed it!
