I ordered an adapter from Carputer Shop on eBay for my 13902 headunit, and it works great! It says TOY1 on my cable. Maybe there is an older GROM verision that has problems with the 13902 headunit.

Looking to buy one for my 1999 IS 200 with 13902 headuint. My CDs were stuck with ERR3 on the display, and now I have taken the changer apart and removed the CDs. Has anyone got the GROM adapter to work after removing the CDs on a 13902 headunit?
