Reviews and Problems with Garmin GXM 30 XM Smart Antenna
Showing 1-10 of 42
A bottom-rung $49.00 XM radio works better than this
22 December 2009
Summary: 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.
Summary: I use the GXM 30A antenna connected to my Garmin 396 to gather in flight weather. Having weather is great, however, this antenna has let me down 50% of the time. The USB cord is designed to fail. It's so fragile that under normal use you can only hope to see it last for a year or two. The cost to replace the entire antenna is $500. Garmin wants $110 to repair the cord. Just build a durable product in the first place and charge me once for it.
Summary: I originally got this when I had a StreetPilot 2820. I tried the FM Traffic but it didn't seem to be giving me very accurate information at the time (the FM Service seems to have improved since then). Anyway the bottom line for this unit: - it's about the size and shape of a hockey puck - it is a specialized XM Radio. That is why it's so expensive (even then it still seems a bit expensive to me).
Summary: I purchased this receiver in anticipation of a trip along the Blue Ridge Parkway just last week. I knew it would be remote and was looking forward to music and radio (NPR) while riding. The setup with XM took some time. I didn't realize the unit had to be on and outside, not in my garage when the "activation signal" was sent from XM. Nonetheless, once set, the unit was easy to connect to my Garmin Zumo 550. Once on the road however the reception was poor.
Summary: I bought this to go with my Garmin 7200 and have used it about a week. I got it mainly for XM reception, but also for the XM traffic and weather updates. I am still checking out the usefulness of the traffic updates, but so far the XM reception has been great. I don't even have to put it on the dashboard. I keep it on the console by the shift in my Armada and still get all three bars showing full, meaning at maximum, reception.
Summary: I am mixed in my feelings regarding this product. It does work, just not as well as the other Garmin weather products. If I had this first, I am sure I would have liked it better. It is tough to see the weather on a small screen if you have it zoomed in tight. Other than that it is good.
Summary: Purchased my Zumo a year ago. Just purchased the GXM30 satallite antenna. I wished that I buoght them togeather. The combination linked to my Harley's sound system prouduce crysltal clear sound. I truly would recommend this combination to all.
Summary: I love my Zumo 550 and GXM30, but the small USB-style connector that connects the XM with the motorcycle mount seems to vibrate itself loose on my unit and then the unit loses connection. I am not sure if I am missing something or not. I had Garmin send a new XM antenna and that didn't solve the problem. I just bought myself a brand new mount and am hoping that works, but am not confident.
Summary: I have the Garmin StreetPilot 7200 and this antenna was required to use the unit for XM. I got rid of alot of clutter on my dash by having both gps and XM in the same. Make sure that this antenna is up high! I have it mounted on my semi truck driver side mirror arm, and in eastern Ohio and PA it's cutting out alot. Pros: One thing on the dash. Cons: Cuts out even when the south sky is clear...
Summary: This product combines both XM and XM Nav service. When connected to a supported radio, XM works with the XM Nav options, limiting some of the XM channel information. Additionally Radio enters standby mode for no apparent reason.
