Query: Misleading Concerning XM

Garmin says that only an antennae is needed to use the built in XM capabilities. That is not correct. The Garmin does not have an XM receiver in it so you have to buy a special "antennae" listed at $270 and $200 on Amazon. It is the only way to use the XM function and is 1/3 the price of the GPS itself. Garmin are taking advantage of customers and are providing misleading advertising implying that only an antennae is needed. To those of us accustomed to XM and what typical antennaes cost it is quite a shock when we go to use all the capabilities of the GPS.
