In looking for a new head unit I am also considering a harddrive based job.

Seems the IT storage factories are waking up to HDD-in-car
opportunities. They are looking to increase storage capacity, reduce
size but particularly to increase reliability for what is seen as a
hostile operating environment (shock, temperature, vibration) of a car.

There are HDD untis out there - one which shares 20Gb between SATNAV and
MP3 but given the above I couldn't comment on the reliability.

Anyone have any experience of them?
