Hi Sniggley,
It's good to hear you have nRoute working for you again. Cheers!!
I hope you don't mind that I moved the thread to the Garmin Mobile PC section. It's more appropriate here. I left a link to it in the original spot.
Terry is right, if you have even a passing interest in moving to Mobile PC you should take a look through the Mobile PC section. If nothing else read through a couple of threads that compare Mobile PC and nRoute.
You have discovered what everyone else does when they contact Garmin about Mobile PC ... utter confusion. It is about the most poorly understood product they have.
Yes, it's just like you take a Nuvi and stuff it into your PC. The interface and features are just about identical to the Nuvi. It's a really nice nav program, one of the nicest. The graphics are superb and for basic nav functions it's really simple to use. However, if you really like the 2d map display of Mapsource and nRoute, this will be lost on you (as it is on me .. I never use 3d mode).
No, it doesn't hold a candle to Mapsource for the sort of planning you like to do (so do I). Mobile PC does have a couple of features for modifying routes that Mapsource does not. If you like the way Mapsource works for creating routes and viewing and playing with them you will likely have difficulty adjusting to Mobile PC.
As Terry said, it really depends on how old your map version is whether it might be improved in the areas you are interested in. But if it came with 2 unlock codes it's pretty old and likely has a lot more up to date data almost everywhere!
Also as Terry said, the maps in Mobile PC are already compiled, like the GMAPSUPP.IMG file that Mapsource produces to load onto your eTrex. You can't use it in either Mapsource or nRoute.
I have an eTrex Legend HCx and it makes a great receiver for nRoute (you have great taste!). I have it working with the software-only version of Mobile PC but it's not just plug-and-go like it is with nRoute. That is, it will not work with Mobile PC without some help.
