The day I bought my car, I called SiriusXM and had my subscription that was in my M3 transferred over to the Prius… actually what they had to do was to cancel my Sirius account and then create an XM account and then transfer my credit to the XM account. They got the radio ID from the VIN number, etc. and it was all A-OK and I got my Howard Stern! YAY! I called XM this morning and wanted to add the NavTraffic, NavWeather, etc. to my subscriptions I was told at XM that my car doesn’t have this functionality, that there is only the radio. They had me go to channel 1 and see the radio ID number, which I did and read to them and they confirmed that that unit only receives radio station programming and not the NavTraffic, Weather, etc. This seems weird to me because there is functionality in there and I see it, but when I try to click on any of these features on the radio, it gives me a message saying “An Active XM subscription is needed for this service”. Also what is weird is that our 2011 Highlander Limited had the NavTraffic, Weather, etc. turned on as part of the 90 day free trial, and the unit in the Highlander doesn't seem nearly as sophisticated as the one in the Prius. Any idea how I can get these features?? Tom.
