That was one that I can recommend to my fellowship
Bought the Extension because I wanted to extend into my driver arm rest.
Removed the top 12V power outlet and used a Dremel to carve a slight bigger hole. Fit like a glove.
Really really like it. Unless you knew anything about the car you might believe it was stock equipment.
I installed the Infiniti CarPlay unit back in January of 2021 and have been using the system ever since. Recently, I damaged the USB cable and contacted UNAVI for support with this specialty cable. They not only gave me the cable, but also the USB mount conversion free of charge to prevent reoccurrence, as long as I paid for shipping. Great customer service and would recommend to anyone.
