$1500+. Send it back to Garmin for the WAAS upgrade.

Seriously, I think you just take it to a Garmin dealer. Surely it is a
field-replaceable item. But it wasn't in my Northstar M3, had to send it to
Canada for replacement of the battery.

My GNS 430's message says my Memory Battery is low. What is the procedure
to change this and what is the cost?



Thanks
