I fucked up, whenat the car wash earlier, I was vaccuming my inside. I saw that my navi unit was a bit dusty, so being the stupid ass that I am, I tried vacuming the dust off the screen, and put a nice big scratch down the middle of the Navi., with the end of the vaccum. Any suggestions on how to get rid of this scratch?

 

If it's not too deep, maybe PlastX? I use it to rub scuffs off the outside display on my cellphone. Not sure if it's safe for touchscreens tho

 

Plexus should work. If you can't find it in an auto parts store, try any marine/boat store.

West Marine carries it.
