Customer's confusing on android 5.1 head unit

JOYING 10.1" Android 5.1 Car Stereo with Bluetooth GPS 2 Din Head Unit Android Car Radio Audio Autoradio In Dash Car

1. I noticed from the website that there is a new 6/26 update to the firmware.  Can you please provide me instructions on how to update?

2. My radio seems to continue to drain my car battery after I turn the unit off.  Its drawing around 300mA from the battery.  If I don’t start my Jeep for 2 days, I find my car battery dead.   How do I make sure the radio is powered down and no current is being drawn from the battery?

3. The FM Stereo app does not stay on a station.  It randomly starts searching after being locked on the station.  How can I turn off the auto search?

4.I am unable to get some apps like Netflix to play the video.   The app will load and I can select movies.  However, the movie will never play.  Why is Netflix and HBO Go not compatible?

5. The user manual references inserting a SD card to increase memory.   Is there a slot that I can add an SD card?

6. I have a $G LTE USB modem for AT&T Carrier.  Is this possible to connect?   https://www.amazon.com/Netgear-Aircard-Unlocked-Beam-340u/dp/B013PRKCT8/ref=sr_1_2?ie=UTF8&qid=1468360562&sr=8-2&keywords=4g+lte+usb+modem

Kind regards,
