I have something similar from aliexpress. I wonder if they all use the same silver box and put their own stickers on it. The carplay functions work great but the audio output does not sound as good as the phone connected to the combox via bluetooth. Music lacks bass. Nav directions are distorted because the levels are not set correctly. Mic input for phone calls or siri can be hit or miss. Some of the newer versions of this system use the combox rather than aux for audio input which sounds better.
