OK, so the navigation software can be replaced (so long as its compatible with the installed processor I presume?) - but what about the maps?
Most ebay auctions just say 'preloaded with maps for Australia' but don't say what quality or coverage those maps are. Asking questions like "how good is this map? Does it cover x town" gives responses like 'yes it covers all of Australia' which doesn't fill me with confidence. I heard one extreme example where maps outside Sydney or Melbourne just show major roads, and completely miss even the large regional towns all together, let alone any town with population less than 10000 people!
How can you tell if a map is detailed enough for your needs ie will cover the towns you want - or is it just assumed that they're all pretty good now?
And then what happens if you find a GPS unit where the map isn't good enough for your needs, and you find a map that is - how can you tell if your more detailed map is 'compatible' with your nav software or GPS unit?
Is there a FAQ or tute that I can read up on all this?
Thanks in advance...
