Looking for a replacement for Garmin 185. Unit is from 1997

Thanks

I don't have the chip anymore, but I have a 185 you can have cheep.

Thanks but this one will be only good for the canyons with the existing chip I have so having two useless ones won't help. If I get the chip I may be interested in your unit as a spare, Thanks

The chip I am looking for is marked MGUS202SS It's the older Micro G charts. Please check your old units. Thanks again
