Hi
Just bought a Ed30 that was registered in October 2007
It has a RNS510 b with an old firmware I believe because the owner was not sure if the canbus needed changing.
I want to search postcodes and use a sd card so want to do the firmware update.
From what I have read, I need to update the FW to 3810a, then 4020 and apply the canbus fix (just in case I have an old one)
I also I believe I need a copy of the maps (which i do not have)?
Is this correct?
I also have a parrot 3200 fitted, will this need reconnecting after the upgrade?
