I have just bought the 5380 & 4380 (Navman). Both look really good and hoping to get out and try them in next couple of days

What are the latest software versions of these? and do I need to dend for upgrade?

My versions are:

4380 - 1.6.8 (17/11/2005)
Serial - 0505A30050633

5380 - 1..11 (16th December 2005)
Serial - 0601A30010515

Just want to make sure it's all up to date and ready to go.
