My 2006 CD 22 Cruiser had a Garmin 178C chartplotter and sonar when I purchased it. It came with one media card which is a very small card with a "handle" on the end (not the mini SD card). I want to have coverage of some parts of the ICW and some lakes and rivers. According to the Garmin website the data cards that my unit uses are not used anymore, being replaced by SD cards. They offer some of the coverage I want on CDs. So, I assume you download the info from the CD (in the computer) to the chartplotter. Is that correct?
If my assumption above is right the various areas I want will add up to be very expensive. Am I better off to purchase a more up to date unit with built in maps? If so, and I purchase a 400 series Garmin unit can I use the same exterior antenna and the same sonar/temp sensor mounted on the transom?
Thanks in advance for any assistance.
