I also have a Laramie 1500, and I have the same problem with the weather radar. It will only the radar for a few seconds, and then it will re-paste he entire screen and the radar data goes away for several minutes. When it happens it usually does not ever come back. Very disappointing with both SiriusXM and with Ram for not fixing this. It is a simple software update, it should be fixed already. Every time I mention it to he dealer, they just scratch their heads like they didn't even know that they truck has weather radar as an option on SiriusXM. If they haven't fixed it by now, I doubt they will ever fix it.
