"Is ur Nuvi 255W set with SW v5.00 is US set, GPS ID 0827. No JCV or Lane assistant support. but with ecoRoute ?"
Yes, that is correct
"Patch to SG/MAL sw v2.60, JCV not work with CIty Navigator north America 2010.1. but U will get Lane asisstant, and also get Waypoint Icon showing while navigating in, which suppose make the map be cluttered, u May not like it."
OK, then I would like to just try the "Lane Assistant".

I switch back My Nuvi 255W US from Sing/Mal firmware to US firmware. and Test on City Navigator North America 2010.10.
Yes, you're right. US firmware Not Support JCV & Lane Assistant, but I can see ecoRoute feature.
Then, I Switch my Nuvi 255W from US firmware to Taiwan firmware, JCV & Lane Assistant Not support too.
Take a minutes to Switch it from Taiwan firmware to Sing/Mal firmware.
Yes, Confirm ! only Sing/Mal firmware support CNNA NT 2010.10 lane Assistant.
