Navigation Display -- Does it work with Truck Camper

I know that my friend's camper interfered with the Sirius radio reception in his 2014 RAM. We bought a magnetic base Sirius antenna from Radio Shack, mounted it on the top front of the hood, removed the existing XM cable from the back of the radio, and plugged in the new antenna. I works very well except north of the Arctic Circle and in some deep rock canyons or very heavy wooded areas. So he is very satisfied. He does not have the Nag System.

I run Street Atlas 13 Navigation on my laptop computer in my truck. It worked all over Alaska even up to the Arctic Ocean. It didn't work thru the Eisenhower Tunnel on I70 but I didn't think any radio signals would penetrate that rock fortress.

I am beginning to think that I will not get the factory Nag System because it is not that user friendly and my truck camper probably will interfere with the incoming signal.

I am surprised that no one responded who has experience with this issue.

I don't know for sure... I will hazard a guess though that most factory installed nav systems are also coupled to the SiriusXM satellite radio units, i.e., the easiest (cheapest) route for the manufacturer is to combine the GPS antenna and the satellite radio's antenna into a single mount. I know all the Dodge, Jeep and RAM vehicles that I've owned since 2008 have been that way and I would imagine that most of the vehicle manufacturers do the same. That isn't to say that you wouldn't be able to relocate the antenna, but, it probably wouldn't be cheap or look very good. If you are going the TC route, I'd save my money and get a third party GPS unit. You'll also find that map updates, for many 3rd party GPS makers, can be free or reasonably priced while the "updates", at least for my MOPAR nav units are several hundred dollars each (the one for my '11 RAM won't work with my '13 Dodge Journey, or so I've been told, I'm not willing to turn either one into a brick to test that), while Lifetime Maps came with my Rand McNally/Good Sam RV7725. Personally, to CMA, I have the 7725 sitting on the dash right above the built in nav system and we use the two of them to verify our route. The RV7725 also has custom POI's that are easier to load and control than the built in system. I can use the Good Sam route planning portion on their website and then when completed, I can download it to the 7725; makes life a bit easier for us.

A third party nav system wouldn't have the antenna issue as they are standalone devices and have the antenna built in or have ports for an external antenna that could be placed where line of sight could exist from the dashboard. I even have an external antenna for my computer to use several mapping programs from my laptop.

My Pioneer in dash GPS has the antenna mounted at the base of the windshield without issue. I know Rams have an issue with the stock location and TC overhang.

Don't see why not. GPS uses 28 satellites and it only needs to see four to calculate a position.
