Echomap sonars don't device ids don't seem to map well

[thepkc]

https://www8.garmin.com/support/download_details.jsp?id=4749 this is the software for the garmin fishing sonars suite. It is a little bit unusual since it contains a lot of subfiles in an update folder. The main update appears to be for all the various devices, but I found it quite hard to map any of those files to device ids.

These devices don't use the 006-B* profile but many different categories: https://www8.garmin.com/support/ch.jsp?product=010-01864-00 for example

I'm not sure if support for those, or a way to find the mapping would be possible... but I'm open to suggestions and happy to suggest some code for that:)
