You lose some functions like Language Guide and Ability to display (More Data) on Nav Screen.(There are also a few unusable icons.)
You also have to use RGNVoiceEditor to add support for TTS Voices.
The POI Search is also not as nice as US.
Changing to JPN will not really be worth it for you, I think you lose more than you gain.
There is also the risks involved.
You could look at Purchasing de Luxe Firmware, I don't know the specs ? but you can Google for it.
hello hello friends, it's very hard for me from now on. Each week i have 2 days of weekend, never enough to do anything.
Today I decide to test my old 1490. From beginning, i try to flash CHN v2.5 and device just runs loop from loader screen forever, I can't flash back to original as device appears and disappears from flash software. I just open it, lol, it breaks the face cover. Finally, I can't see anything to mod to reset when I can open this one. I feel sorry about this, although i have 3790 for a pair in case.
Finally within google and many forums, i can manage to have firmware 360 of japan to run. It's very beautiful to my eyes in every options that i feel missing in US version. Then i discover that the sound doesn't work. Looking back this thread and i need to use voiceeditor. Flash again, i can select French and English as my language instead of missing like before, but sound doesn't work at all. I think I did mistake when reconnect the speaker wires. Open case again... too much hard and nothing there. Finally, I flash back to US firmware, sound just works.

My question is, how can you manage to have english sound like English_American Jill? Any tips?

Thx a lot
