Doesn't work most of the time
For USB C Splitter for Android Auto / Apple Carplay
This thing seems to be *extremely* picky about what kind of cables you use, what kind of phone you have, and what kind of vehicle you have. I have to admit that I have seen it work, but I'll be damned if I can figure out why or how to recreate that combination. How something that (theoretically) should be so simple can be so finicky is beyond my patience.

Hi Robert,
Thank you for your feedback. You're correct that the setup is very picky about cables and phones that are compatible. As I mentioned in the product description, many phones are incompatible due to not supporting USB PD or various software quirks. The most common problem people have when setting up is that the board passes through the power delivery connection from the charger to the phone. As a result the connection from the phone port of the board is not reversible and only works in one direction as mentioned in the instructions. This is not typical for USB C so although it seems random it's actually quite predictable. Considering you were able to get it working at least once I'm guessing that is your issue.
I'm more than happy to assist with any issues with your setup including replacing your unit if necessary. Please contact me with the details of your setup so I can help out.
Regards,
Rohan
