PartsArena is a stable product used by thousands of service engineers and technicians across Europe and North America using disparate datasets on a variety of Windows Mobile devices. The current solution holds the data on an SD card. PartsArena uses a very small amount of memory to run in. We do not have instances of 'erasing the PDA'.
All of our data is authorised to be used in PartsArena by the manufacturers. If you buy PartsArena you are assured of not being in breach of copyright laws which OEMs take very seriously.
The Windows Mobile 5 version is due for release in the next couple of weeks.
Keep your eye on our websites for more developments.
