Data connection with Bluetooth or wifi tethering

[bnwgraaf]

I have just bought a Pumpkin AA0495B-A01 and am figuring out how to set things up the best way.

If I understand it well, I am able to get data connection through Bluetooth tethering on my phone. This seems to work.
But it is also possible to get data connection with a wifi hotspot on my mobile phone.

Is there a reason to choose especially for Bluetooth tethering or to choose for wifi tethering? Which is best or what are advantages and disadvantages of both ways?
Of course I would connect Bluetooth for making phone calls and maybe playing music from my phone.

Another question: if I use Bluetooth for phone calls and maybe data connection, is it still possible to also connect a Bluetooth ODB2 adapter, or can I only connect one Bluetooth device at once?

Hello,

After you connect your phone with the Bluetooth to your car stereo, it can also connect to the Bluetooth OBD2 adapter.
