My car has a standard Pioneer head unit. I had a Pixel 4 before switching to the Galaxy S21+. The cable I used for my Pixel 4 doesn't work with my S21+ so I bought this one. For some reason the S21+ is very picky about which cable to use, unlike my Pixel 4 which worked with everything. for "Android Auto" on this cable. Some of the reviews are not very positive. Maybe there were some bad batches where the quality control isn't up to scratch? I do not know. I personally have very few problems connecting to the head unit. I would say that 9.25 times out of 10 the connection to AA was stable.
