I seriously thought it was a HDD =P
I mean every company tries to cut corners everywhere. My clues were that they used an outdated chip, with outdated OS included, with outdated pioneer software engineers.
So i thoguht it was safe to say that they were using a HDD.
lol my bad, this is a completely useless post then, feel free to delete this whole topic.
The older Pioneer units used HDDs and they can be swapped out, maybe thats what your thinking of.
These are updated now... or you can say that... windows CE
