Looking to upgrade to gps and fishfinder. I have been looking at the Matrix 67 which has both for under $500. I dont know all there is to know about this unit other than just reading product info. but for that price I wont to know just about everything and to me info. from someone who has one would be valueable. So if anyone that has one or owned one let me know your take on this unit or maybe another unit that has both features at a better price. Another Question does these units have map chips already or do you have to buy seperate.

thanks
