My touch control stopped working on my navigation unit (JBL E7028) and finally got the issue fixed. While looking for parts and instructions , I've noticed there wasn't anything on the JBL unit . However, using info on Prius non-JBL and other Toyota units, I was able to ID the part needed (part # LQ070T5GC01) and also take the unit apart and do the repair.

Found the part on AliExpress by searching for "LQ070T5GC01". Note: the new parts will have a longer connector but still have 8 pins ( like the OEM part). Price will range from $13 to $100+.

This forum is where I always turn when looking for answers and I thought it is my chance to give back. I've created a step-by-step PDF (2.2MB) from all the pics (along with URL-s for the sources of "inspiration", just in case someone else has the same problem) . See attached.

Attention: while this is not a difficult project, things might not turn out as expected ( items/parts break, additional issues are discovered...). If not confident, turn to professionals for repair assistance. There is always some risk involved with DIY projects.

Thanks!
