My wife just had the dash replaced for free on her '08 IS350. Before you could literally sink your fingernails into the dash it was so soft. Now it's hard and smooth like the rest of the trim. I'm sure there's thousands and thousands of vehicles that need a new dash and it'll take a while to produce and replace them all.

@Fernando Diaz Nin From the videos it looks like your digitizer is physically working, it's just that it's reading the touch with an offset from where you're physically tapping. Unsure if this indicates one or more of the traces aren't repaired or not. But I recall reading there's some way to get into a service menu to initiate a recalibration of the touch accuracy. You might want to find a link with instructions and try that before yanking the unit out a 4th time.

My general thought on the chipping of the glass was it didn't really matter as much as you think. It's actually an extremely thin copper trace sandwiched by two pieces of glass. So even though you don't have a clean, flat copper surface exposed like on the flexible cable portion the liquid circuit writer will be pushed up against the glass sandwich and thus the microscopic trace in there. At least that's my theory. :) I spent 1+ hours trying to chip glass to get a flat trace under there without any luck. Only a couple of the chips resulted in enough copper where I could get the tip of my multimeter to get a signal. I then gave up, did the circuit writer pen, baked it under a 60W bulb for a couple hours to dry it, then tested everything and it was good. You do really have to wait a long time for it to dry and become conductive, particularly if you put it on real thick.
