Winnipesaukee Forum - View Single Post - installing Garmin lake-vu chip question(from a dummy)

Cobalt 25 · 07-02-2017, 11:50 AM

Just bought the lake-vu chip from Garmin for my 740S chartplotter. Turned on the unit, installed the chip, waited for chip verification to appear on the screen, then pressed BACK, CHARTS, NAVIGATION.

I then scrolled to Winni (from here on the Cape) and did not find any data, such as depths, on the screen.

Am I doing something wrong? Do I need to be on the lake before the data shows up? Also, once I install the chip do I have to reinstall it every time I go to the lake?

thanks,

Peter
