In case anyone missed it, the Yaesu FTM-350 now supports the use of an external GPS via the COM port. You need to download the latest software from Yaesu's site which adds additional settings in the SET menu. The relevant setting is under the APRS/PKT menu, item E16 - COM PORT SETTINGS. Setting #3 - INPUT can now be set to GPS. Additionally, there is a new setting #2 called OUTPUT that will allow you to use the COM port to output the GPS data.
