I also read that newer versions of firmware also provided additional features, bug fixes and performance improvements, obviously! So I started doing a lot of googling and reading and found a wealth of information spread all over the place about how to upgrade both the firmware and maps on the RNS 510.So having successfully updated both the firmware and maps on my unit I thought I would write a guide to summarise, in one place, how I did it.First I will describe how I did the firmware upgrade, then I will move on to how I updated the maps.1. This information does not pertain to the US spec RNS 510 – please read through comments for info – these instructions are specific for UK and ROW (Rest of World)I was starting to find the maps on my RNS 510 were getting a bit out of date, after all I had never updated it since I purchased the car in 2009.
