Hello,
I'm using a Samsung Tab 4 7" (Android 4.4.2) as navigation device mounted on my motorcycle:

It works quite well (for my needs), unfortunately it loose the GPS signal very often and get minutes to lock satellites again. Also, sometimes it takes minutes for a "cold" start, other times it take just seconds. This behavior appears to me as to be somehow erratic and random.
So I decided to buy an external GPS Antenna, namely the Globsat BU353S4 equipped with the SiRF Star IV chip:

Just after receiving the antenna, I discovered that my Tab 4 version (SM-T230) does not support external devices plugged to his USB port. In other words, it does not support the USB-OTG (On-The-Go) cables.
Even the power led on the antenna stay off after plugging it to the Tab 4... no signs of life. : (
Somebody else is experimenting this kind of problems in plugging an external USB antenna to an android phone/tablet ?
What (cheap) Android device I should look for?
I've read that the Google Nexus 7 (model year 2013) support OTG natively. Any experience with such device? Should I buy it?
Thanks in advance for any hint/suggestion.
