Saved route on 6250 is different to that using MyDrive
Despite this, the route that gets put on the satnav often contains spurious route changes, which seem incapable of being removed - the web version has differences to that on the satnav & I have found no way of changing them. Looking at MyDrive, the route is correct - not always so on the satnav.
Some changes are minor but very irritating, such as going over the top of a junction on a dual carriageway rather than continuing on the main road. Others introduce completely different roads and are often unsuitable for a larger vehicle or take me off the main road and into a housing state, or whatever. This is particularly irritating near where I live, which is in the process of having the main A14 dual carriageway upgraded - I know which junctions and routes are open but I can't make them 'stick' in my planned route, so the satnav version of the route incorporates a number of spurious route changes, which don't seem to be able to be overwritten. Luckily I know the area, so can ignore it but that may not be the case elsewhere in the country.
All very frustrating & defeats the aim of pre-planning the route.
Is there a way of ensuring that the route I plan is the route I get on my satnav, or will it forever be overwritten by whatever an eternal piece of software decides is what I meant to go?
