Nokia HF-310 Bluetooth Handsfree Kit ZGB000051100 New genuine part

This is a bluetooth handsfree speaker unit.

This comes with windscreen suction mount and connects to your phone via bluetooth. A car charger and cable are included and once charged it can be used as a freestanding speaker unit. The call answer / end button also doubles up as a button to start voice controls (if your phone has this function)

We used to run these in our VW vans and they're great little units for the price.
