The latest update is a step in the right direction and also a step back! Since it takes over 25 minutes to download and import contacts from my iPhone it really renders my 400 useless for communication on shorter commutes. It loses the contacts as soon as the phone disconnects from the TomTom and the 25 minutes cycle starts again. Even sleep mode loses contacts. During the importing time it is now even impossible to answer calls from the TomTom. The phone rings in the headset but the only way to answer is on the phone itself. The contacts should be stored on the device itself for at least the last phone that was connected just like the original rider.
I too also have the hoarse voice instructions however it is intermittent. Sometimes clear and sometimes hoarse..
