Hi Ronnie,

Navcoder is the software that you need (you have the correct link above)

To use the software you need a laptop (with software installed) and an I-bus interface, you have some choice here, you can

a: make one (from the diagram in the zippped install file)
b: buy one, from either

or

http://www.reslers.de/IBUS/payment.html

I made mine and it works very well, (after a blown transistor or 2).

Then you connect your circuit up to the cd changer interface lead (3 pin, its located in the boot and requires some trim removal to get to) and your laptop, thats it follow the menus on navcoder.

Hope this helps

John

P.S this only works on factory installed (or OEM retrofit) SatNav & TV modules.
