Title: A bottom-rung $49.00 XM radio works better than this
Review: My husband (an over-the-road truck driver) used this XM antenna on a StreetPilot7200, and it lost signal *constantly*. Also, if your StreetPilot7200 fails like ours did (along with 2 replacement rebuilt units) and you have no intention of ever buying another Garmin product, then you are stuck with a basically worthless XM antenna and out a lot of money. Begrudingly, at the end of the string of failed StreetPilot7200s, we bought a cheapo $49.00 XM radio from Walmart, and it has worked fine for several months now and does not lose signal like the GXM30.
Is the review positive or negative?
