Thread: Venus Series City Navigator China NT CHS 2011.11

Maybe its not limited to China or Taiwan devices, maybe the bin file works only for a limited amount of Nuvi models

You could be right. My info was gathered some time ago and has not been updated. Maybe each .bin file is like a plugin that every Garmin device can recognize, read in, validate then execute if applicable. If not every device, at least on new models and old models with firmware upgrade. But I simply have no access to every Garmin device to verify this. I would encourage readers of this forum to try the official shifted China map on their Garmin devices with and without the bin file then compare the results.

Guess not. The code in the bin file receives GPS coordinates from the GPS chipset directly and if the coordinates are not in China territory the code has no effect. So you have to be in China to test the code, unless you know how to modify the code to respond to coordinates in your area.

I believe Tom mentioned about the bin file, not ISM.IDX. Also, I don't quite understand what do you mean by Junction/Intersection change. Could you post a before and after screen capture for comparison? Thanks.
