I have Just been to the Garmin Website, looking for software updates for my Kenwood KNA-G430 GPS unit.
There was no Update that I could see that was specific to the KNA-G430 unit, as this unit is now discontinued, but I did find a link to KNA Series software version 3.90 as of July 9, 2009.
I currently have Software version 3.50 installed and would like to know if the KNA Series software version 3.90 as of July 9, 2009 will work in the KNA-G430 unit.
Hi Syd, I would think that the "KNA series" software would be ok in your unit, but, I would be asking the Garmin that question, just to be sure. They have answered any query I have had very promptly.
