PN-40 question

[+Tahoe Skier5000]

Hey all

 

I've had my PN-40 for about two years now and have used it quite a bit. Aside from the following issue I have with it, I love the thing. I just came to realize after using my Garmin Oregon for a bit that the map redraws on the PN-40 seem a little excessive. When I hike around I like to leave it on the map page. The PN-40 seems to redraw the map (track log and waypoints) at least every 5 seconds. Granted it doesn't take too long to redraw, but it seems like it just redraws too frequently.

 

Thankfully, the topography on the map and the location arrow stay put when the unit redraws the map screen, but the track log and waypoints disappear for a couple seconds while it redraws.... thus making it kinda hard to follow my track or navigate to a waypoint using the map screen.

 

I think Garmin has a better design with their maps. I only notice my Oregon redrawing if i pan the map.

 

Any suggestions on either, a) how to fix this, or how to deal with it. I don't know if its something I'm exaggerating and other people don't have a problem with it, or if it is a known annoyance.

 

Thanks

How big are the map files you're draw layers are overlaid on? I tend to keep mine around 300-500 MB for performance. It's said you can go as high as 1.2GB on a cut map before performance degradation begins, but If you have 4 corners of each cut map meeting each other, you can easily exceed the 1.2GB files size being displayed.

Are you using imagery on your maps? I get crisper performance using just the topo data--probably because the files are smaller as TotemLake alluded to.

I figured it out... silly me I should have known, but the map orientation was set to course up rather than north up. I didn't even think about that being a problem but apparently it causes the map to redraw much more often with these pn-40's...

 

Anyway, I changed it to north up and it seems to have fixed it!

 

Totem, the maps i have on the gps right now aren't that big... probably 40mb at most and they're the topo maps, no imagery or anything.

It's the aerial photo imagery that really takes a lot of storage per square mile.

Coincidentally, I'm downloading some more as I type.

I'm planning on my annual summer trip up to Kennedy Meadows and I think I'll come up from the Bakersfield side this year rather than your side.

I'm always course up and I don't see the major problem you describe when using aerials or topo.
