Hi i'm new here, got directed from another forum i'm on. Ive tried everything to get the new fw on my rns510 but the unit wont recognise the discs, ive gone through about 10discs ha. I was wondering if anybody could send me in the post a copy of this fw, the fw that you need if you brick it and a copy of maps? I'd obviously pay you for your troubles via paypal, and also after retrofitting my rns510 the mfsw buttons wont operate it and i get no info in my MFD anymore. Anybody know why? Thanks
