First one will not work (it is a VW RNS-510 unit)

Second one will have limited compatibility (address books not shown on unit) and not work with all newer phones. It is also a Euro unit, so it is hard coded to expect a British accent I dont recommend this unit.

You want a 8P0-862-335-J or newer BT unit for newer smartphones.

Here is a list of RNS-e compatible BT units and functionality. You dont want a Euro unit as I mentioned, unless you want to speak with a British accent!
