also found out yesterday that the quote did not even use my NCB so I can use it on my other car which will make that quote cheaper as well, .
Remember the Navtrak units battery fails after about 5 years and it constantly drains power from the batter, resulting in flat batteries after 5 days left unstarted. If you can, its best to disconnect them. Most are under the rear parcel shelf and you can simply disconnect by removing the rear seat and disconnecting the multiplug.
I normally turn off the battery isolator as I only use the car at weekends, mine is over five years old but not sure if it connected around the isolator switch or not, anyone know?
Same for me, so I have used my NCB for my daughter's car insurance - V5 in my name but car really hers - saved £1000 on what she was being quoted!
