aekhong,
Great thanks to create this page of tutorial. I saw a thread from other forum, (believe u know which one, let me know if u are not, i will PM you) It seem that SiamMarine mentioned there is possible to convert back to US. I am beginner on this GPS firmwave, appreciate if you could help to understand thier explanation ?
"@AussieDJM
Yes, you can always come back to US firmware with gupdate.gcd(US) because it has the same boot.bin(us)
More information...
This picture is rgn for 7x5 series US(Whatever HWID) --> Sg/Mal (HWID 1069)
After flashing rgn ,Nuvi will have boot.bim HWID 1069(Sg/Mal) instead 870(US).
So it need modified rgn to come back to US., and just simply upgrade to higher or lower Sg/Mal firmware by using Sg/Mal gupdate.gcd."

Also, the sg/MY 2.30 can apply on 3790T(US) ? (Concern on the model with "T" - traffic)

I was aware of this possibilty via other forums , but I have a 3750 US and I'm wondering if it worth or not to convert to SG/MAL. On your first post you said is possible to 3760 and 3790, so not possible to 3750 , am I right?
Another question, is really true I'll lost the ecoroute function? or only my data till today?
Thanks

Now I think we have a way to go back to US firmware for Nuvi 3790us converted to Sg/My.
