I think I have sat on the side lines long enough on the topic of GPS' or, more specifically, RV GPS'.
I have a JVC audio/GPS system installed in my MH. It works well. But it doesn't allow for a few things I think all GPS' should have:
Ability to customize the route for both shorter distance AND longer distance on the same trip (or leg of a trip). Much like Google maps does on line, I long for the day when I can touch the screen and drag the planned route over to a route I prefer. This seems to be major gripe I have with all current GPS' - not enough customization.
Having said that, I would look for these features on a GPS...
> display that shows a lot of detail (roads & POIs) without having to zoom in to a ridiculously small area/scale;
>> my JCV doesn't show anything of detail until I get to less than 1/2 mile scale; that is awful. My Garmin does a better job of showing more detailed maps a zoomed out scale, but still not enough for my liking. Tom-Tom is no better.
> I would love to see a GPS that tells me ahead of time about a POI or set of POIs I want to know about (e.g. rest stops). With the small scale one needs now to see these it is too late to stop by the time they show up on the map.
>> how come I can get smart phone apps that pinpoint rest stops and truck stops based on my location but a GPS can't?
> map display must show: next turn direction, distance and time to next turn (including what it is - e.g. exit number, street name), posted speed limit, remaining trip time, estimated time of arrival.
>> the GPS' I have looked at that might be suitable for RVs are the RVND 7710, Magellan Roadmate 1700 w/RV map set, MAGELLAN ROADMATE 9165T. I'm not sure any of these show me all the map detail and information I want on the map screen.
> the web sites for these GPS units show far too little detail of what a lot of the screens look like.
> the web sites should have a demo one can run through to see how the GPS units work (this would show me what screens show what information). That I have to go to a store and drag a working unit outside to test this functionality is stupid. The makes of most GPS units miss this important point. I think it why so many get returned.
> a smart phone app is much more useful for POIs than any GPS I have looked at. They allow for searching for specific POIs, sets of POIs (again, the example of rest stops). My iPhone is even a bit more responsive and useful for detailed and quick map routing in many cases.
To end on a positive note: I'm OK for now with my in-dash JVC. I like the blue tooth, the voice-over of the announcements over what ever audio is playing.
I suppose I could go on. But for now I'm keeping my $350 until I figure out the next step to take.
oh - so far I have found that a GPS is no substitute for a real good navigator in the passenger seat.
Wish me luck in finding a GPS system I like.
