I am wishing to update my Jaguar's GPS nav system with the latest DENSO Navigation DVD (AUS21) (from https://jaguar.navshop.com.au/shopexd.asp?id=35).

How is this done? Is it just a matter of taking out the old disk and putting in a new disk.

How often do the Australian gps nav system disks come out? How old is AUS21?

Thanks in advance

 

You may have your answer by now but yes, it's a simple process to update by just running the new disk. Instructions come with it. Whereis release an updated version each year so best to check their website for when they release the updated version to ensure you get the latest.
