Question: How would the back up camera work if put on a 32 foot 5th wheel trailer?
Document: Thought by buying a maggellan product that it was a good choice.Was installed for two weeks and during that time ,sometimes it would not work when in reverse.Then it would not work at all,fuzzy picture like someone put tape over lense. After speaking to customer support and updating software on the 1700, they decided that the camera had an issue. As of this date I am waiting for my replacement. Hope this solves the problem....
My husband bought a new Ford Transit Van with no windows. After a few days, we knew we needed a backup camera. Did some research and found a 7" Magellan GPS and this back up camera that would work together. The 7" display was perfect for both applications. Took it to Best Buy to install (less than $100) and they mounted the camera on the windshield and threaded the normal plug into the ceiling of the van so we eliminated the cord dangling from the GPS.
I was concerned that mounting this camera on my left side licence plate would make the camera not work well. I had it installed by my regular mechanic. Love this product. Wide angle is amazing. This is installed on a 23' motor home.If you see a motor home on the road, that little window in the center of the vehicle is my bathroom window and No I can not see out of it from the drivers seat.
I purchased this back up camera with the 5255T-LM GPS directly from Magellan in December, 2012. Installation was not too difficult in my 2013 Sonata (I had installed others before - plus Youtube videos helped)and the camera worked well for about 4-5 weeks. It then began to work intermittantly so I checked the connections and power supplies and all were good.
The guys at Best Buy had trouble getting the camera to come on line for quite a while, but finally it connected to my Magellan GPS. It's on the back of my pickup and I use it to line the trailer hitch up. The biggest problem is that it's refresh rate is really slow. It's fine for just checking behind the vehicle, but when in motion, you can be two feet further in the time it takes the screen to refresh.
I gave up! So after much thought I decided on a different course of action, I cut the power cord and soldered an extension in place, bought a 25 foot RCA video cord and extended the transmitter into the cab of the truck, it now works from a grand total of 3.5 feet away and that is if I do not mount the receiver part on the back of the gps.
They used another from a different model that really didn't fit...but it worked. I discovered this when I took a peak inside my Xmas gift. So, I really did them quite a favor. That didn't help me when I called back after Xmas with my installation question. So, disgusted, I dug the wires and transmitter out from behind the plastic panel and left it in my trunk. It all began to work properly from that point.
I called customer support and had to ship it back for a replacement at my cost, so add another 14 dollars to the initial cost. The second unit arrived and I tested with the 9 volt battery and it appeared to work so once again I started the install, it performed in the same manner so I again contacted customer support and they started me back thru the entire return saga again after refusing to refund my money.
I have had a magellan roadmate 1700 for about 1 year now and decided to get the back up camera. My original set up was with the reciever double sided taped to the back of the gps, however this interrupted the GPS's signal and would display "acquiring signal" from time to time. I then decided to remove the reciever from the back of the GPS unit and everything works PERFECT!!
I removed the plastic plug, ran the wire to inside the trunk lid, then push the plastic plug back in place. The camera works great but you have to wait 10-20 seconds for the GPS to warm up with it's warning signs before the camera comes on. Camera has a fair to good wide angle color picture. Camera also has a up/down adjustment. I recommend you would view the installation video on the Magellan web site before installing.
Answer: Well, not sure if there is enough range for the transmitter to send a signal to the receiver.  You can try it, and if it doesn't work, return it right away.  You will need to have a power source for the camera's transmitter like your backup lights wiring so the transmitter will send the camera image when you put your vehicle in reverse.  On two backup cameras that I have, I've had to not use the quick wire taps for the transmitter cord and, instead, solder the wire on to your existing wiring since the quick wire taps will come loose over time.  I found that even the plastic covers inside the trunk of my car interfere with the reception, so I had to mount the transmitter inside my trunk compartment instead of hidden inside the cavity between the plastic and the frame of my car......and it's a Miata which is a very short car and short distance for the transmitter to work.  I don't know if the transmitter has to be inside something to protect it from the weather.  I assume so.
