I am not that tech savvy, and have never owned a tablet, but I get the impression really they are just a larger version of a smartphone?
Quite often I use my smartphone as a sat nav, or music store, or even as a hands free phone (in the X7) ..
is it possible for me to fit a tablet into the dash of the van, probably with a 'view' of the sky, so I can
A) add a sat-nav app and use it like I normally do
B) play a store of music through a headunit, via an aux in - got one or two of those lying about
C) access wifi if near enough a source, to update, download etc
D) be able to navigate with a blue tooth generic ODB port reader for general diagnostics
E) communicate with my Lexia cable/obd - on the move
F) be able to view a couple of old reversing cams I have lying around (Cable digital cameras from memory - using phono leads I suspect)
G) be able to communicate with a wireless camera
H) be able to be a hands free phone (presumably communicating with a smartphone)
I) be able to pick up digital tv with some DVT plug-in, and an ariel
J) be able to communicate with another tablet nearby, to read/write data between
K) be able to be voice activated ( I think my Samsung phone has this although never used it)
My present phone and last were both android, and I am happy with that..
if any of the above is possible, the tablet I guess needs :
Wifi connectivity
USB port(s)
a line-out
Bluetooth
a power supply from a usb socket etc
is that it? will it work?

thanks as always
