I use that version of max sea and it works perfect in my laptop with a GPS bluethooth antena (you donīt need a GPS) type Holox-BT541-Bluetooth First step get the port were the antenna as been found. If for example the port is high, 2 digits (example 23) it dont works, so yo must go to control pannel COM PORTS try to configure in 4800 and change the port number to 1, 2, 3 or 4.
Then in maxsea in UTILITIES CONFIG DATA IN/OUT put the same port you had configued in control panel. Email me and I send you a detailed information with images. Hope this help. Cool winds
