I am nearing the 3 month mark of ownership of my 2010 Prius IV NV and my XM trial is about to expire. They are quoting $212.12 per year or $56.76 per 3-months for XM+NavTraffic. While I have really enjoyed the service and NavTraffic alerts, I am not sure if the service is worth it at that cost. In the past I remember XM offering a $77 per year plan, but it appears that it is no longer offered since the merger with Sirius. Does anyone know of any current discount codes or promotions that are available for the XM service? Thanks in advance!
