Here a couple pictures of the GXM31 Antenna wire harness and connectivity. The antenna has self contained XM module transceiver that provides XM Weather/Music to the 540/545 units.

The local West Marine and Boaters World didn't have one I could look at. Were should the GXM31 be mounted? Tom, what are your thoughts on 540 vs. 545? Con |

I've flush mounted four so far three under tee tops and one under a biminis. The only difference between the 540 and 545 is screen resolution. Both great units. Tom |

The antenna and transducer for my 545s arrived today. Meanwhile, Ive been using the unit simply hooked up to pos and neg inside the cabin of my Tug. The internal antenna has only lost reception once going past a former nuclear plant. hmmm. Only took about 5 mins to reset doing a whopping 10 against the ebb. I suppose a faster boat would take longer to reconnect...but then, a faster boat may not have the interference a cabin does. The 5" screen has 10 times better resolution than the pre vector units. Damn it. These units are almost RUINING the art, the skill to learn how to navigate Columbia River day, night, fog and bottom over the past 30 years and this little box has it all...nearly everything Ive learned...deadly accurate, in vivid color. Hey, hehe, it's all good. Get one. mk |

I ordered a 540s, but now I am almost regretting not ordering the 545s. I guess I will go ahead and find out if I made a mistake. |

You'll be more than happy with the 540. Tom |

Sorry Grant. "Get one" kinda implies there are no other worthy options. I used my 545s as a reference for screen resolution, vector charting & internal antenna results. It has a memory card & sonar options you may not need. Comments on the extra expense of memory cards; I am not certified. Prior to this 545s, I would take GPS readings and soundings from two different machines and write them down by hand. Then I would transfer this info onto a expensive Navigation program installed on my hard drive that allows me to customize waypoints, soundings etc. Eventually print it out. Point is, recreational boaters probably dont need all this memory/bluetooth crap. Just get the highest screen resolution and vector chart enabled GPS you can afford & enjoy. mk |

I need help deciding between the Garmin 540 and 540s. I have 24" Regal sport boat that I use in the Delaware and Rehoboth bays mostly for pleasure boating, no fishing. The bays can be quite shallow so I want [the GARMIN 540s] to help keep me out of shallow water. My boat has a built-in depth finder, and my installer tells me it would be quite expensive to replace it with a Garmin [SONAR transducer]. Should I stick with the 540 and use the boat's [SONAR transducer]? The Garmin is much easier to read versus the boat's built-in depth gauge. |

I don't recommend trying to use the Garmin SONAR with a transducer from another manufacturer which was intended just as a depth sounder. If you select the Garmin SONAR you should install the Garmin transducer. Is the current depth sounder's transducer installed as a through hull, and in-hull, or a transom mount? What type of transducer do you plan to use with the Garmin? |

My radio is mounted in the compartment above in my t tops. My GPS is mounted in my center consoul. The XM wired seem very bulky. I find it imposible to fish those up through the tubing. It my be easier for me to by a XM ready radio.Has anybody experienced this problem?? |
