Help required i want to update my RNS510, what upgrade path do I need to do as ive searched the net and I'm even more confused,
Specs.
Part no. 1T0 035 680 F
HW H06
SW 3970
Maps 7690
Man fac date 2011
Some google searches say I can go straight to SW 5238 ?
Some say latest for this model is SW 5274.
Whats the difference and can I go straight to 5274?
Some sites say I need to update the SW to load the latest V15 maps as they are too large for the current version as the hard disc partitions are changed by the newer SW?
Thanks for any help
