So let me ask this. If I created a custom profile that was named the same as his, would a recalc by me of a route received from him automatically use my same-named profile?
No. The custom setting is stored with the basecamp route, rather than in a commonly used profile. (In fact, the custom setting isn't a 'profile' at all).
It has it's advantages in that when you change the settings of a route using the custom setting - the changes to the route in Basecamp are implemented immediately.
If you change the settings for the ones stored in a profile that is used by many routes, then you can expect a long wait while it recalculates every single route in the Basecamp database that uses the same profile.
None of the settings in the profile, or route settings are ever transmitted to the Zumo. They are there just for the route that Basecamp calculates. Since Basecamp sends the plotted route in the form of thousands of ghost points (gpxx route point extensions), The zumo knows exaclty what was plotted in Basecamp - but if it recalcuates the route, then that information is lost. If you use the smae maps on the zumo as you used to plan the route in Basecamp then and either you do not deviate from the route or you turn off automatic recalculation, then the BAsecamp route is what you follow.
But if the route does get recalculated, then it is the zumo settings that are used for the recalculation - and that can vary between zumo models.
Devices like the 590, 595 and XT could store different routing preferences for Car, Motorcycle and Off Road. If the Zumo had routing preferences set for Motorcycling, it would use the routing preferences that you had set in the Zumo for Motorcycle. Similarly with Driving Profile in BC and Car profile in the XT.
If you created your own profile and gave it a name in Basecamp, the Zumo would not recognise it - in which case it defaulted to using the routing preferences for the Motorcycle.
The gpx file sends only the name of the transportation mode (eg Motocycle) and the name for the routing preferences (eg Faster)
The 590, 595, XT and XT2 all default to Motorcycle and Faster unless the gpx file contains an alternative that it recognises.
The best option, I find, is to have all preferences turned off in Basecamp, and use Faster Time. Create a custom route and make changes to the settings for that route - eg change the avoidances, ferries. If the route actually changes, then there is a place to add a shaping point. Keep doing it until it makes no significant changes. Practice repositioning the shaping points rather than adding more. eg two shaping points at 1/3 and 2/3 distances along a particular road are often enough to stop it from straying onto a faster road.
When your done, assign the route to use the Motorcycling profile (with all avoidances cleared).
But no - there is no way to get your friends preferences into your route. I believe that the data is stored in the Windows registry. I did once export my Basecamp registry, changed the settings and then reimported the registry to see if it would bring back the previous settings. It was only partially successful and I didn;t follow it through. I'm starting to think like the poor chap who made the mistake of working out how long it would take him to listen to all of his CD collection, and realised that he didn't have enough life left.
