So there is a new update to the Maps for the 2016 model year but I'm beyond the 3 years of included updates. I can purchase individual updates at $87 or 3 more years for $135. Clearly the $135 is the better deal as it comes out to about $45/year. Is the a better/cheaper way to get updates? I've heard some people just get a new SD card that comes with 3 years of updates but I read a thread, either on here or the facebook groups page that some of those older cheaper SD cards give the system fits. Any ideas?
