Which Navcore and which map do I need for my tomtom one xl?

Hi,
HELP..
Totally new here and looking round all the posts I am now confused.
I have a tomtom one XL (recently updated to app version 8.010) and it has maps V710.1571.
Boot system 5.3026.
Which Navcore version do I need and what version of western europe maps do I need.
The fast activate bit seems straightforward as not many versions to download.

I put this together http://www.navitotal.com/forums/showthread.php?8302-8.412-Setup

It depends on whether or not your ONE XL has a card slot.

Hi, yes my ONE XL has an SD card slot and I have a 4gig SD card waiting.

1. You need to update your bootloader before your XL will run your 4GB card. If you use the 8.412 setup in post 2, there is a bootloader file in it titled system5.5128. Rename that file to system, by deleting the 5.5128. Copy this file into your current setup, overwriting the existing system file. Disconnect & reboot.

2. Use
Western_Europe_880_3865 OR
Western_Europe_880_3865 with Automatic Installer & Patcher

Copy the new navcore, new map download & a copy of your device's ttgo.bif file to your 4GB card. The 8.412 in post 2 is pre-patched. The 3865 map with Auto Install & patch will do it's own thing. Put the card in your unit & reboot.
