Quick update and plea for guidance:

In the end I opted for the Gamin Montana 610. Got a new one, including GB OS 1:50,000 mapping for £391 from Blacks.

I spent a slightly frustrating Saturday trying to get my head around how to make it all work.

So far I have loaded Garmin Express and BaseCamp, and then added in OSM mapping into BaseCamp to compliment the OS map.

I tend to plan routes in Google maps. I have exported these as .kmz files and loaded them directly into BaseCamp and also used GPSvisualizer to covert them to .gpx files before loading to BaseCamp. I also looked at loading the .gpx files directly but was not sure where to put them on the Garmin folder.

I can open the .kmz and .gpx files no problem in BaseCamp, when they show as a track.

I gather I need to covert these to a route to get route guidance. When I double click the track and select "create route" it gives me an error message. I am using streets in the middle of Bristol - so not sure why it is erroring.

I can create a route by changing the BaseCamp profile to direct routing - it then does not error, which seems odd. However if I then change this profile back to "motorcycle" it takes the route all over the place.

Essentially I want to do two things:
1. Create a purely 'on road' route in Google maps for a typical week tour (split by days) and make it a route on the Montana where I can get route guidance on my selected route
2. Create a trail riding route (mixture of on and off road routes) that does the same

Any tips on where I am going wrong?

Cheers
Andy
