I'm looking at a cheap 6 inch android phone that will simply run the Torque Pro app and run Waze. I've found the following two on Amazon and they look fine for my purpose and was wondering if anyone had an experiences with them or had any alternatives? A 7 inch tablet is too big to retrofit within the satnav housing, same problem with a 7 inch touchscreen paired with a Raspberry Pi.
