All, Just wanted to confirm I can also now move MapTech created Routes to my newer GPS unit GPSMap 545s by sending the routes to my Garmin GPS 76 first. Since the 76 interface is Serial, I purchased a serial to USB cable and software from Radio Shack and after playing with the ports, was able to communicate and make transfers. Next I used Garmin MapSource to input the route info from the GPS 76. HOWEVER, I was using an older version of MapSource Version 4. and this would not see my SD card. Using the Update option under "Help", it would not update. I went to the following site
http://www8.garmin.com/support/download ... jsp?id=209and downloaded the 6.15.6 update to my desktop then installed. Now my MapSource sees my SD card and can transfer routes to it. NOTE: It's important to place the SD card in the GPS using you want to use FIRST so it is set for that model. I plan to try this on my older large (10") Chartplotter very soon. Bob
