Somehow (!), after following guidance posts, I managed to properly remove my Blue&Me unit from my 62 plate Ducato X250. The mileage on the dashboard no longer flashes. Hurrah!
Having had this success, I threw away the broken Blue&Me unit. Then I had an OMG moment! Would there be a circumstance where I had to do the procedure again

So, is there a way I can save my current proxy setting to be able to ‘reinstall’ it if I need to in the future. A bit like a Windows restore point I suppose. Thanks
