Hi all, just purchased and used for the first time the below tank bag. It holds a sat nav in a rather good position. Have holes so you can run cable out of the sat nav holder. Fully expandable and if you phone the bloke it appears he does ones with straps instead of magnets. I'm suprised by the amount it holds and it fits rather well on the D6.
If you have any questions feel free to ask here and I'll try my best. I hope the link below works but if it doesn't the ebay number is: 130345219946
