Hi,
I just bought a Zumo 400 (has UK maps installed) and downloaded the City Navigator® India NT maps for it to the SD card but it is not picking up the India map (check with settings->map->map info). I've tried 2 different SD cards, and have formatted them multiple times (FAT and FAT32) without any luck. I cannot install it directly to the Zumo as the India maps are 230MB and there's only 198MB free. I have put MP3s on the SD card and they play fine.
I have also deleted the gmapprom.* map to make room and then installed the India map directly to the Zumo but the Zumo ended up without any maps. I renamed the supp maps to gmapprom.* but that didn't work either. I also tried using mapinstall to install a small part of the UK map and then directly downloaded the India map to the Zumo but it didn't work.
I am not getting any errors from the Zumo, it just fails silently. Perhaps the unlock code is wrong and it isn't reporting it.
I am currently in India with my Bike and a mapless GPS. I'd really appreciate some help (I'm computer programmer so be as technical as you like) as it's delaying my trip around India and I don't want to buy an Indian GPS.
The folders in the Zumo 400's garmin folder are:
GPX

The files in the Zumo 400's garmin folder are:

The SD card has the 3 files below in the Garmin folder:

Thanks,
