Doing a bit of research, it appears that the model numbers indicate if you need to buy an accessory to get Traffic updates or not. If there's a "T" in the model number, the traffic accessory is bundled. If there is no "T" in the model number, you need to buy the traffic accessory separately. That said, I think it's safe to assume "LM" in the model number of a Garming refers to Lifetime Maps.
