Hi all, I upgraded to the PCCM+ in my 997 about 18 months ago - and since then I've only used the radio on the unit.
Last weekend, I tried to use the USB port to charge my phone and access AppleCarPlay - but the USB port was totally dead (I tried various USB cables inculding an original Apple cable but still no joy...)
I had flat battery a few weeks ago and had to jump-start the engine, so I'm wondering if that my have affected the USB port in some way...
Has anyone esle experienced this / have any suggested fixes?
Otherwise, I feel this could be (another) expensive trip to the Porsche garage...
My 997.2 C2 also has a USB port that seems to do nothing and it occurred to me that it was for a flash drive to play music. My car had 56,000 miles on it when I bought it—not sure if it was always this way, but at least you’re not alone on this one!
I don't have any experience with PCVM+ but is it maybe for music stored on a USB flash drive and not for connecting to a phone?
No. I charge my phone with mine all the time. Should be hot for power. I do know some people rewire their units so they can connect in the back on the extra USB port for a hidden *wireless* CarPlay dongle, but right out of the box it should be hot.
