Good morning. I've taken a second plunge into L322 ownership. MY first foray was with a 2005. It gave me the Range Rover bug (along with a lot of bills and frustration) Round 2 is in a 2010 with 124k miles. Can someone advise how I can update my maps? I haven't looked in the back to see if it's DVD based like my '05. If so, can anyone recommend a supplier of the update? Thanks in advance.
