I was in the same situation as bluewing. I bought a 334 last August. Used it a couple of times. This spring when I went to Canada it started acting up, finding and losing position and the color display went bad. Sent it into Lowrance a month ago. After 3 calls to 3 different tech support people I finally found one that would really listen to my complaints and requests to upgrade it to the 522c. I have only used it once since I received it from Lowrance, but I like it. I believe they have corrected the problems with the new model 522 that they had in the 334. I think you will be happy with it. I have mine on a fishhawk on the dash and the windshield doesn’t seem to interfere with the GPS signal.
