looking to replace
 

the satnav/tv headunit in my 02 x5 to a single din clarion unit
but from what iv been reading and seen when i took the unit out the connections are nothing like the normal ones for a direct replacement.

the plug i need to use is in the battery tray in the boot and to run all those cables to the front would be a nightmare.

is there a satnav to normal connection adaptor if you get what i mean haha??
