I'm looking for some help upgrading an older Raymarine
RL70 Plus chartplotter
firmware to version 4.09 or 4.11. It is my understanding that there's a C-Map
NT card with the software
upgrade. The Raymarine documentation
claims to upgrade, you insert the upgrade chip into the top chart slot, turn on and RL70+ will upgrade its firmware.
Local Raymarine repair shops want $50 for this, which seems a bit unreasonable for 5 or 10 minutes of work. Also, the places that can do this are inconvenient driving distances on LA freeways.
I'm hoping someone has the upgrade C-MAP
NT card that I could beg, borrow or use for a reasonable cost. I'm happy to pay shipping
and I promise I'll return the card. I could also do this at your place if somewhere near Long Beach CA.
Thanks in advance,
