I have just bought a SL350 MY2009 facelift model. The satnav is working but the Post Code coverage seems very poor so I wondered whether upgrading the maps would help at all or perhaps there is some other way of improving the post code coverage.
I attach the Engineering Screen so that those more knowledgeable than me can determine what firmware / maps I currently have as I cannot work this out. From what I have read here I believe that the firmware is quite old but I cannot see what map version I have.
Any advice would be very welcome.
PS Sorry the photos is the wrong way up, its fine on my phone and on my PC so I dont know why its come out this way!
