Much appreciated. Helps if I spell it Nav Trak as well rather than Nav Trac. Throws up much better results !
Contact made - engineer coming out next wednesday !
Thanks Catman
Navtrak now disabled by the very helpful Tony from Cobra. He said the units can be in one of 4 or 5 different places depending on what serial number is on the unit (they have the serial nr on their database). Worth contacting Cobra to have yours disengaged before ripping the car apart as it may not be where you think !
Total cost = zero and a very pleasant chat with a guy who really knows his onions and loves his job.
