like the previous poster, i usually take the approach of loading at least 2 map styles for any area i'm visiting, an overview/road source to zoom level 13 or 14, and a highly detailed topo source to level 15. in BCN, those would be:
- "CalTopo US 24K Topo Maps": great detail with many...
keep in mind that each zoom level is exponentially larger in terms of storage space consumed. i find that level 15 for topo or road maps is sufficient. i'll do 16+ for sat/aerial imagery but only select locations or else it really eats up the storage.
to elaborate (i was on my phone earlier)...
Copilot downloads all the maps after install, so it requires no data connection beyond the first time download (unless you want traffic updates). all of the US & Canada including lane-assist and POI info is around 2GB (or you can just pick East Coast...
in general, i don't think there's any point in trying to use the ham's GPS output for navigation on an Android or Apple tablet. many tablets come with integrated GPS receivers that work just fine for general trail nav when mounted inside the cab. in fact, i would make sure to purchase a tablet...
i'll second the vote for Copilot USA for on-road navigation (turn by turn, POIs, routing, spoken prompts, etc.). you perform a one-time download of an entire country's map and then you're good offline (about 2GB for USA)...
after about 6 months of use, my Sony 10.1" tablet had the same issue with any charger (even factory). however, it would only discharge while plugged in *if* i had the screen at full brightness and everything else on too - like bluetooth, gps, cell data, etc... changing it to be 94% brightness...
seems everyone's doing LEDs lately!
i'll add mine to the list - rear hatch window mounted camp area light, full writeup here: http://offroadpassport.com/forum/showthread.php?t=4595
i went with the brightest strip i could find in 4500k natural white, black PCB, waterproof and adhesive...
thanks!
i simply installed some of the heavy duty resistors meant for that purpose. i put them in the taillight harness since it was easy to get to. one resistor per side took care of having LED bulbs in the front and back.
this company makes a sleek dock mount for lots of tablets: http://www.proclipusa.com/tablet-holders/device/samsung/galaxy-tab-4-8-0.cmsv
i use one of theirs for my Sony Z2 10.1" tablet and it is my stereo system, on-road nav, and off-road gps with topo maps. before that i had a XOOM with a...
there are number of similar hardware solutions, mostly used by folks for playing songs or videos stored on them (which i believe you must load using a desktop computer)...
however, i am looking for confirmation of a specific mapping app working well with any of these devices, and in what way...
i guess my main question that remains is can any of the apps work well with external storage and if so which app and which external device are you using?
...or does everyone just pony up for the 128GB iPad if they are serious about using it for mapping?
thanks especially for the tip on Gaia vector - because of your comment i was able to find that they also have had their own styled vector topo maps based on OSM data since v9 (currently on v10.4.3). i'm guessing they're similar to the OpenAndroMaps that i'm used to since they use the same base...
i'm very familiar with the current possibilities of Android devices for mapping/gps use in overland situations, but i get asked fairly often about using an iPad instead and so i wanted to do a little research...
i did re-read RobRed's excellent iPad Navigation FAQ...
