I have old routes that I am battling to remove from my device - I delete them manually on the device but they keep re appearing even after a hard reset they re appear. Please help.
I suspect you sent them to your nuvi using Basecamp or some other program? You need to delete the relevant files (normally named temp.gpx) in the GPX folder on your nuvi. Once you clear out that folder and then delete the routes/trips on your nuvi they will be gone for good.
