I have to give up on making the ph JCV work for US nuvi 2595.

I have tried to use the PH and SG/MY firmware and using the US boot.bin but end up having the SOFTWARE MISSING message. I tried a couple of times to do the RGN method but no success.

If I use the PH and SG/MY fw only as boot.bin, the GPS will hang in loading software.

So there is no luck here. :-(
