Default Uconnect 8.4 NAV Hang

Hi Guys,
I have a 2017 GC Overland with a Uconnect 8.4 NAV that intermittently hangs at the "loading" screen during startup. If it sits overnight, it generally (but not always) works fine. If it's shutdown for a short time, like a fuel stop, it tends to hang. A forced communications bus reset generally (but not always) clears the problem. I updated the firmware to V17.43.01, which I think is the latest for a 2015. Any suggestions for a fix? Or, suggestions for an OBD scanner that will scan the communications bus errors? Thanks.



_MY15_Can you recommend a device that will read error codes on the bus and report the source of the errors? Thanks.
