garmin 235 fish finder not working

[cmitchell]

I have a Garmin 235 that the depth finder stopped working.It constantly reads 700-900 feet.I had the unit checked and they said it is not my transducer.The shop said that they can't work on the unit but Garmin will fix and update the unit for $200.00 flat rate.I know that this is the smart way to go but I spend so much money on my boat that if I can open it up and sodder a wire or replace a fuse than my wife might keep me around a little while longer. Thanks for any suggestions

Only my opinion but I would not open it and try to fix,especially without the schematic

Clifton<br />I would not open it up as most units a filled with nitrogen to protect from water vapor.<br />I think I would try and reload the firmware. Is unit a GPSMAP235 sounder? I did not see a straight 235 sounder on their web site. Contact Garmin and see what they suggest as the best way to go.<br /><br /> http://www.garmin.com/products/gpsmap235s/download.html

Thanks Boatist,it is a gps235map and I read on the garmin web site about how I could down load the upgrades for free which also rests the unit.I thought that maybe this would fix my little depth problem.My only problem is that I don't have the proper cables for power and for the usb port.Where do I buy those?Thanks again for everyones help

Should be able to get them at the Garmin site.<br /><br />I know Magellan has different things for their's.

Clifton<br />I would again suggest you contact Garmin tech support. It is a free call.<br />Their web site has cables. I think I would bring a battery and power cable to your PC amd just get the interface cable, but call them first and see what they say or if they have a upgrade package.<br /><br /> http://shop.garmin.com/accessories_for_product.jsp?sku=010-00119-00 <br /><br /> http://www.garmin.com/support/
