I wonder if the trick of combining POIs would work. Was told in an AU map thread by Bushwalker8 about pooling the POIs of different maps, Topo and CN or CN and CN. This is confirmed by syzygy telling of returning Chinese tourists using two maps in a Garmin bought on holiday, one in Chinese enabled the other English disabled. Because the Western unit has no Chinese keyboard, they input in EN but are then able to negotiate to POIs on the Chinese map. Maybe might work if this map is loaded but disabled, with a modern topo as the 'visible' enabled map?

Carty & yourself may be well be right with dual CN's eventually clashing, I know it's not recommended but have never had a problem with the Topo/CN combo but that said it's not something I would leave long term anyway if nothing else purely for the sake of multiple layers slowing the unit down.

The primary interest is not navigation it is - for short periods - the ability to "stack" the maps to pool all the POI's together for far deeper and more effective searches which I find very useful at times. The POI's have always been quite different between Topo & CN, but now also between the differing CN's. To me the benefits of this far outweigh the risk of a minor blip at the time, maybe not everyones cup of tea but I'm sure there are others who would also find this a useful technique. It's one of those little things in life you don't really appreciate until you try it.

What happened is: they bought or brought back a foreign (outside of China) Garmin GPS device which can display maps in Simplified Chinese, but has no way to input Chinese for searching. Without searching capability, the device is close to useless. To enable searching, they actually install two CN China maps, one in Simplified Chinese and one in English. The latter is unchecked all the time. Now, to search a POI they simply enter its English name in PinYin and the POI found will be displayed on the Simplified Chinese map, ready for navigation.

There seems to be no problems reported so far with two such CN China maps installed.
