Reversing/GPS device recommendation

[rambada]

Good afternoon all

I am wanting to add a Reversing/GPS device to my D4. But I am wanting the capacity to add in other options. This will be a stand alone and not a replacement for the in dash system. Can anyone recommend a device that has the capacity for:



Reversing camera input
GPS
TPMS
GAP Diagnostic IIdtool


TIA.

If you are computer savvy, all of the above can be achieved through an Android tablet. Not straightforward, but doable.
