For those wondering how to remove the Scion logo from your headunit trim ring....
DIY at Own Risk
Acetone will remove this silk screened logo from the black plastic without discoloring the plastic. Takes a couple minutes wetting and rubbing, but it comes off relatively easily.
* Some members have reported that acetone has made the h/u trim ring appear faded, or scratched looking.
1 - Please make sure to thin down acetone with water if you have pure acetone - nail polish remover contains acetone but is generally too diluted already.
2 - make sure to use a cotton ball / q-tip / microfiber cloth / anything non abrasive to rub the silk screened logo off as to avoid marring the surface of the trim ring itself.
This has really complimented my Toyota rebadge, now to eliminate the Scion splash screen from the headunit boot up sequence..
