The external GPS unit of My lowrance globalmap 3500 has died. I have been quoted around £200 for replacement. Considering replacing with 5150c as can get for £299 and use old card. Have seen the 3500 for £442. So is the 3500 a superior model to the 5150c because would then just replace gps unit. Advise to clarify my confusion would be gratefully received.
