Hi guys, i know there are some " how to " and info to retrofit sat nav, etc,etc... but everything is on pre-FL. Mine is FL 59 plate, and allegedly the wiring has changed plus some of the functions were improoved as well. kind a like the idea to retrofit whole FL sat nav, but it is too much work, so would like to retrofit BT only. On FL model the BT works with MFD display, where you can see info about your phone, signal, battery, caller's name or number and even you can copy ( not sure ) the contacts list. so wondering, has anyone of you did that and also what do i need ( part numbers ) to do this job?
