I originally just went to www.satnavdisc.co.uk and without looking ordered what they were offering, it arrived within the week cost £80.
However that did not work, SD card unreadable. So I contacted them by email and they asked for the code on the top right of unit (either e or w), version info and a picture of the existing map card, a new SD card was in the post and my version is now 17_A. I hope that this helps anyone wanting to update their map.
