1st - who did you buy the radio, hub adapter, and hub from? (what do they have to say? ... before I can consider offering support) An Ebay seller, "Genuine AutoTech', no complaints with them, their support was to exchange the radio, which they did. So, this issue is with two different 2021 radios, two different adapters, and two different media hubs. So, I tend to think there is an issue with my particular truck or some setting within the radio.
2nd - The Hub adapter looks like a near exact copy of ours (they even copied our wire colors. dang!) I tried 2 hubs, the one pictured from "bicycleparts99" and another from "wallacecjdr" which I returned it was the wider hub with 2 USB ports. The adapters are from "CarPlay" out of Canada, recommended by the radio seller, and the other, I think from "motorcycle126"
3rd - What's the new Radio PN? I can't read the Part Number sticker on side of the new Panasonic 4c radio?? (but it appears to be 2020 or newer version with SL02 or SL03 screen... I can tell from the back & should support AA/CP ). P/N 68518262AF
4th - Your 2017 laramie/limited should have Dual Zone Auto Climate correct?
(do the temp controls work correctly. Did the SXM button and BuCam show up/work yet?) yes everything works, dual zone, cameras, etc.
5th - Are you running a custom engine tune? No completely stock truck
6th - Did you enable Smartphone Projection in radio settings? I am guessing not? don't know where I would do that.
7th - What "Application Version" is the radio running ?
(key in RUN. Press and hold : driver side TEMP Up + TEMP Down + Front Defrost for 5-10 secs for dealer menu) I will have to do this.
Thanks for the help!! much appreciated.
