This is a great device. Unfortunately it does NOT work with the Vodafone v1615 or (Tytn II). Apparently Parrot did approve the device but later retracted it after complaints.
See Parrot forum
Parrot UK Forum / HTC TYTN2.
The problem is that the phone does not transfer the call to the MiniKit on a regular basis, and when this happens it is difficult to get the device working together again.
Once Parrot get there act together and release a fix this will be a great device.
Any one else having this problem?
