Which sony xperia do you have? Can you post a link? I read an old sony xperia z4 review that stated it was superb in direct sunlight.

I have run into this same problem with both my iPad and my Garmin. This may sound silly, but you need to tilt or rotate either your head or the display. You can see the brightness change and probably get it so the display completely disappears. It is annoying but easy to work around.

The light emitted from most displays is highly polarized, so when viewing them through polarized glasses you have to be lined up just so. At some point I want to do a post on this in much more detail. I learned all about this when I repaired my very old depth gauge with some recycled material from an old lap top screen.

Z2-SGP521-4G not as bright as Z4 but but enough for my eyes. The difference is only 2 DIN's speaking with photography terms so hardly recognizable with eye sight.

After having spent many hours, I'm computer illiterate, searching for tablet mainly for nav. internet, not for entertainment, I've come to decision to buy Lenovo Yoga Tablet 2 10", 16GB +ext. up to 64....250$, I think new.
Could someone more experienced evaluate it?
For me it seems to be OK
And thank you all, dziadek Jacek

I too am cosidering a new tablet because my cell phone carrier is practically giving them away. My current cell phone screen (Samsung III) is worthless in broad daylight and consequently I am concerned about the resolution of various tablet models/manufacturers.

It doesn't seem like any of them have the same daylight visibility of a hand held garmin and I don't want to purchase a tablet only to find out later it's just a larger version of my ineffective cell phone screen.

One of you had (cheap?,) incorrectly made sunglasses with the polarising lens cut and inserted 90° out of orientation. They will not be reducing glare off horizontal surfaces such as water, they will be reducing glare off vertical surfaces such as windows.

You need it for the GPS to work, no need to get the SIM card if you don't wan't it.

Not sure about that particular model but I don't think you need any of the phone functions for the GPS to work. Down load your charts when you have wifi, just uses the GPS receive independently while at sea.

Many Apple models don't have GPS at all unless you buy the cellular-enabled version. Once you have a GPS-enabled version, you don't have to actually use the cellular capability.

Android tablets usually are the other way: GPS enabled, whether you have cellular capability or not.

Different business models, or different engineering solutions...

Don't count on it, most wifi models get their positions from land based data networks... Thou I'd like to know which ones have real GPS, that's of course if there're some.

Old Asus tablet (don't remember model ) Apple iPad Air and older iPad 2 or 3 all have true GPS receiver functions built in. At least the ones I have do.

Where Google location services are concerned, if enabled, your position is determined from surrounding wireless and network towers. If you have enabled your GPS, Google will use it too.

If you own any android device with a built in GPS, the GPS will work independent of wireless and network towers. There are two types of GPS built into android devices. One produces nmea data, the other provides "positional" data that must be converted to nmea data for programs that use nmea data only.

I cannot say conclusively, but my impression is newer devices are adopting the 'positioning' scheme over nmea output. Have no clue why.

I too use the iPad Air 2 with InavX. I have all my boat instruments including AIS repeated over WIFI and iNavX integrates all the data. I augment my Raymarine E7D with it, and I love the fact that I can watch the Radar on the iPad. I typically only use it in the cockpit at night entering a new harbour. I also agree with the Lifeproof case as my first iPad went swimming (at the dock as I was loading gear on the boat).
I use the combination of iNavX, Ayetides HD, DragQueen and as a backup use the Navionics app. New apps appear all the time.
