I have a 2023 Mazda C5 which until recently was playing music from a USB stick via an A to C adaptor. And thennit just stopped - not recognising the stick from either of the ports.

I spoke to the dealer who said that in order to play music from a USB stick I needed a 'c' stick. When I pointed out that it had played via an adaptor for the past 12 months he just shrugged.

I will try a C stick - but does anyone have any other suggestions. For example there is about 60gb worth of files onbthe stick - is that too much for the infotainment system to handle?
