[TG] Replaced DSM300 with CP370 to restore numeric depth reading

[riptyler]

Tom,

Now that I read the PDF and know how to do/send screensshots, I may try that later (prop is off being tuned so not going anywhere). Been messing with power and gain in my shallow water slip and having some success (still get - - - on/off). The slip is good test ground because it runs 4-6' depending on tide (which is the typical range at which we lose numeric depth on the instrument and MFD), so will mess with it while I'm sitting here (nothing better to do).

Thanks,
Rip
