My most distant way point was N 70.511876 W 149.866901, slightly out of data service. My point is; according to Rivian Ads, R1T is an "Adventure" Vehicle including a Rivian Adventure Network (RAN) ????? !!! NOT !!!! Instead, Rivian millennium off-shore contractor techies, chose to not provide satellite entertainment coverage nor satellite GPS imaging coverage or other driver experience features, i.e. functional tie downs anchors (one of my pet peeves). It's my belief that the Rivian millennium techies contractors are off-shore and have never experienced an off-highway grid adventure, their limited experience is smart phones with data connectivity. The first item I installed was a stand alone BT SiriusXM receiver with a "marine" antenna, which is easily BT connected to the Rivian entertainment system. Most people know that SiriusXM receives signal everywhere in US except north of the 49th parallel or south of 28th parallel. The second item I installed was a stand alone NA GPS navigation system which can be programmed with waypoints and alternate routes. Stand alone's are user friendly, more accurate, and have better coverage than the Rivian Navigation System . Unlike most "adventure" owners; some of us use the Rivian as it is meant to be used, solo, off the grid, without support. There are hundreds of driver experience improvements that could be included in the next generation Rivian RxT design. By then, my LE will be well used, worn out, albeit it, highly modified, adventure vehicle. Safe adventures.
