Pc connetion to my E127

[Larry52]

I have purchased a voyage planner I would like to install my Platinum plus Navionics into the chart library Is that possible ? or do I need to remove chip from the e127 and install in to my PC so I could see the upgraded Lake Michigan chart ? Last year I believe I was looking at purchasing the Ray Tech navigation but instead I purchased the Voyage planner . I have read that the RayTech navigation (NOT AVAILABLE NOW)was able to connect to my E127 and what was on the screen would be on my PC, I have a very capable High Graphic lap top I use for 3 d drawing s . Can I hook up the pc to the e127 see the screen of the e127 on the pc In the voyage planner ? , and transfer new routs on to the e127 from my pc ? and if so witch cable do a need and would it be sea talk NG Thanks for all the help through my upgrade projects
