Tx and rx Pin

[edgy4]

Im sure this is a dumb question, but how do i access the tx / rx pin without taking the head unit apart and what tools are required.I am pretty unfamiliar with this kinda stuff and was hype when you said i didnt need a screwdriver.

You don't need to access tx/rx pins or UART at all. That was only for my initial research.

Using what i've documented, you can enable SSH on the head unit and connect to it over the network (just need a suitable usb 2 eth adapter). See here for more details: https://github.com/ea/bosch_headunit_root/blob/main/docs/rootshell_howto.md
