I have used US 1350, 1260, 1490 without mod of firmware and am able to get traffic with gtm25.

the only reqm is that you use city navigator map and not the local malfreemap

I bought a GTM25 and 1350 from US.... flashed it to local firmware JV and LA all works fine just that the GTM25 do not pick up any FM channel...
this is very puzzling....unless they really go and register the GTM25 for sg usage only ....i given up hope on making them work already...hahaha
