I now have my carlinkit working on my 2023 Isuzu MUX, but it took some stuffing around. (this may apply to other cars as
well). So I thought I would share the benefit of my experience and maybe save some others some time. The USB on the Isuzu does not generate enough power to drive the carlinkit. The answer is a USB power adapter.

The one pictured is supplied by Carlinkit, or alternatively, I found this one below, which I think is a bit more elegant and has one less connection
Zemel USB adapter Another tip for those that like music and have some store - I bought an App called PowerAmp ($10.00 one off payment), copied all my Itunes tracks on to a micro USB and now have music without streaming when out of radio range.
