I've been playing with custom Points of Interest files on my Garmin eTrex Vista/Metroguide. As the name suggests a custom PoI is a file of Points Of Interest compiled by a user, for example, detailing the cakeshops in your area.
The Garmin PoI loader seems to work OK loading custom PoI files onto my GPS but sadly the current release of Mapsource does not support the POILoader/Custom POIs). Obviously this is a must have feature for planing routes around custom PoIs. It may be that other mapping systems support custom POIs. Hopefully so will Mapsource in due course.
Obviously there is a lot of scope to prepare a cycling specific custom POI set of which the core would be a vaguely comprehensive directory of Bikeshops (I've got a POI file listing Halfords shops, but that doesn't quite cut it).
I'm sure we've all got anecdotes of being out on our bikes and needing to locate a bikeshop to make a repair or buy some spaires. It would be so much easier if we could ask our GPS to direct us to the nearest bikeshop, and so much better than asking for the nearest station because we were forced to pack'for the want of a nail' (or rather, an inner tube, seat bolt, spoke, whatever).
So.... does anybody know if a bikeshop POI file exists or have access to a (soft) directory which might be wrangled. This might one for the CTC or a bikeshop trade assoc to consider taking on...
