Nexus 7 as a navigator in -32. Minitest

By the end of this year, he became the proud owner of the Nexus 7 3g. I wanted to use it as a navigator, and even more like a tracker through the forest, on snowmobile trips. What came out of this can be viewed under the cut.

From the moment of purchase I was surprised at the huge consumption of the battery, however, after understanding how to turn off all wireless interfaces, I realized that everything is not so bad. Navigation I need raster images. And different, somewhere a good bing, somewhere Yandex. And it's all offline. I found all this in the wonderful SAS Planet program and its cache for Android SAS4Android. At first I didn’t plan to write anything at all about him, when suddenly the weather for the trip turned up wonderful, -32! Here the test of a piece of iron.

As a result, recording a track within 2 hours approximately ate up 0 percent of the charge. On the way back for 6 4 (looked at the gps log) hours, about 5% of the charge was eaten. all wireless interfaces are turned off including nfc. Only gps works. Now I'm starting to think about the equipment of permanent mounting under the snowmobile glass and the power supply for the permanent map display. What is interesting to my father who didn’t like to communicate with computers very much, and he intuitively understood how to move and zoom the map.
Well, here's a short video.
