MN Map chip for older Lowrance GPS?

[guyonacouch]

When I bought my boat this spring, it came with a Lowrance Global Maps 3200 GPS - I'm assuming it's a 2002-2003 model. The previous owner took the contour map chip out and I'm considering either just replacing the unit with my handheld Garmin that I already have a chip for or purchasing a map chip for the Lowrance. Only real benefits of using the Lowrance is a larger screen and the fact that it displays your speed while the map is up which is nice for trolling. Can I use a new chip in this unit or would I have to track down an older chip? Anyone have an older one they'd be willing to part with that they no longer use? Thanks.

I don't see why you couldn't use a new chip, but it would have to be Navionics. Lakemaster only supplies chips for Humminbird now.

An older chip would be a great way to go. Check the auction site. As long as the lakes you fish are on the older chip you would save some cash.

There is one on the auction site right now from a local seller for $65

Gander in Eden Prairie had a ton of Lakemaster chips for Lowrance marked down to $79 from $99 when I was in there last week, they appeared to be for the non-HDS units.

Most older units don't have the processing capabilities to use the newer chips, many wont run over a 1GB chip
