Has anyone had problems with there unit. I update the software frequently but still have more than usual problems.<br />1. GPS went out ( sent it back for repair)<br />2. if I go over 15mph lose bottom. (have moved transducer down more but still have same problem)<br />3.Temp went out. Comes on sporadically.<br />4.Bought the mapcreate 5 software with the unit and now they have a new version out mapcreate 6 but they tell me I have to pay the full price even if I owned a previous version said there is no discount. Seems a little greedy.
