Has anyone upgraded the software on an e series Raymarine MFD for the new dock to dock autorouting? My unit is 4 years old and has never been upgraded, and I'm reluctant to insert the MSD card because the instructions are unclear, and the the MFD does not have the previous upgrades that are referred to on the Raymarine site. I do have an msd chip for Platinum series loaded into the unit, which I guess i have to remove before inserting the new msd,. Do I then remove it and reinsert the Platimun chip?
