USB factory retro fit

[tucpal]

Most retrofits will require vci code regardless what year the
Car is but also depends how the configuration had been setup
at time of build,usb retrofit definately requires a vci code
As all previous ones ive fitted did require a vci code.

Model year from 2013 (13 plate) that has cd400 will not support
any factory retrofits unless the radio has an ident of - UZZ

if usb is already fitted then the radio will support the aditional
Retrofits provididing the radio again is ident- UZZ

good info there i will add that info into a few how to sections

but glad i have been there and done all that now
