I put my 2 Helix 9 on my boat and got a surprise. After sitting on the shelf for 8 months they have no tracks anywhere. Way points are there but no tracts. Could have I shut them off some how. I have searched all my favorite haunts from southern MO. to central Minn. Nothing as far as tracts. Is that recoverable or did I just delete them some how. Thank you for any advive you may have.
