In a recent test we found that the Belkin were a dismal failure, with their Tune Cast and their Tune Base offerings failing constantly during a trip between Cooma and Sydney. Around Sydney and near major cities like Canberra the devices struggled to hold an FM channel and when one did have a channel, the sound was poor due to interference.
At first we thought the problem may have been down to the weather, as the trip down to Cooma was wet and overcast. However the trip back was in bright sunlight wih clear skies and in both cases the performance was very poor.
The failure of these Belkin devices was not surprising as earlier models offered by the company who are as much into bags, wireless modems, and power protection, as they are into iPod accessories, also failed to hold an FM channel for the playing of sound from an iPod device.
