Integrated AIS Receiver

With an integrated AIS receiver, the IC-M506 can show AIS vessel traffic information on the display. The AIS target call function allows you to easily set up an individual DSC call. The Plotter, Target list and Danger list can be toggled on the display. In the M506-21 and M506-41 versions only

NMEA 2000® and NMEA 0183 Connectivity

With the plug-and-play functionality of NMEA 2000 in the NMEA2000 models, the IC-M506 can easily connect to a NMEA 2000 network and interconnect with other equipment. Also the NMEA 0183 input/output can be used for external GPS/NAV interface. The M506-01 only has NMEA 0183.

Last Call Voice Recording

The last call voice recording function automatically saves the last two minutes of the last incoming call. You can also start recording manually.

Active Noise Cancelling

The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call.

25W Two-Way Hailer

When connected to an external hailer horn, you can talk to people on the deck or shore from the radio's microphone and can hear people's reply via the hailer horn. Foghorn and RX speaker functions are also available.

Optional COMMANDMIC™ HM-195B/SW

The optional COMMANDMIC, HM-195B/SW provides 2nd station capability for using the IC-M506 from a separate cabin or tower. Most functions including DSC and AIS functions can be controlled from the COMMANDMIC and can be used as an intercom between the IC-M506 and the COMMANDMIC.

Large LCD and Intuitive User Interface

The IC-M506 is equipped with 132x96 pixels dot-matrix display which is larger than the IC-M504 (132x64 pixels). Reading GPS, AIS, DSC and radio menus are easier than ever. The bottom line of the display shows the software key functions and the functions can be toggled with the left and right buttons.

Great alternative to wood blocks
Size: 17" x 8.5", Color: Gray, Size: 17" x 8.5", Color: Gray
So I’ve used wood over the years to level out my Class A RV’s and even with the wood sealed, there is always one side that takes a beating. I figured I would try these Camco rectangular leveling blocks and was very surprised at their strength. I’ve only used them twice, but both times the RV rolled right up with no issues. The RV sitting on those blocks in the picture is a 40’ Tiffin diesel pusher. My only issue is the dual wheel base for this big RV, is too wide to use the blocks perpendicular to the wheels, so I had to use 3 blocks parallel (see pics) for each wheel, which required me to purchase two sets. Most sites I setup up at fairly level, but this just provides that little extra height if needed.

Simple and easy to use
Color: Yellow, Size: 5.5" Lift
We took a late fall trip to Branson Missouri pulling our Camper. We had to use the Camco Trailer Aid when we got to our campsite and it performed as advertised. Good sturdy product that worked as advertised.

A Must-have for Double-axle Travel Trailers
Color: Yellow, Size: 5.5" Lift
I moved from a diesel pusher motorhome back to a truck and Lance travel trailer. ‘Done with Diesels’ is my new motto. I wanted to check the wheel bearings and couldn’t find the proper way to jack up the side. Some people said jack here, some said jack there, and some said never to use a jack at all, so I was confused. Decided to use some of my leveling blocks and build a ramp to drive up onto and that ended in failure. Either it wouldn’t go up without spitting it out and still wasn’t high enough. I resorted to jacking it up at the spot I thought was best, but wasn’t comfortable with the entire side supported with a small bottle jack cylinder. So I ordered this and it was well worth the wait. Trailer pulls right up onto it and the other tire is ready to work on. The weight is more evenly distributed and certainly feels safer. Obviously this won’t work for a single axle, but for double axles it works for maintenance and makes tire changing a breeze. It’s as good as everyone says it is and has a permanent place in my trailer storage compartment.

Works exactly as stated with a dual axel trailer
Color: Yellow, Size: 5.5" Lift
I purchased this on a hope, I had a trip planned to pull a school trailer 2600 miles round trip and had to use my pickup truck jack if I had a tire issue. I didn't like my odds and bought this ramp hoping it would make things simpler. My second day into driving and I had my first tire blow out. The ramp workers perfectly and I had the new tire on the trailer in 15 minutes. Later in the day, I caught a second tire on the trailer down to threads and used the ramp again to change out tires at a truck stop. I analyzed all the "whys" as to what made the tires blow and fixed it to make the rest of my trip safe and trouble free but this ramp made things quick and easy when i needed it. I'd totally recommend this product and I'm planning to purchase another and leave it with the school trailers for future use. Keep in mind you need at least a dual axel trailer for this to work and have a spare tire to swap to.
