Hello,

1. I am looking for a iMac-based open-sourced program to replace Garmin's MapSource function.
2. Garmin MapSource is only available for Windows-based PC, not Mac.
3. Garmin stopped supporting MapSource with their last update v.16.3 on October 25, 2010, at which time MapSource was replaced with BaseCamp software.
4. I have two Garmin Zumo 660LM gps devices that were built to be compatible with MapSource software (not BaseCamp). MapSource interfaces with City Navigator North America maps allowing users to create custom routes on a PC that can be transferred to the Zumo 660LM device.
5. MapSource is the only recommended software to be used with Zumo 660LM (not BaseCamp). Zumo 660LM devices are NOT compatible with Garmin's BaseCamp, a fact Garmin has reluctantly confirmed.

Since I only have Mac computers, and I would like to use my Garmin Zumo 660LM gps devices, I am looking for a MapSource equivalent to interface with updatable City Navigator North America maps, create custom routes on my Mac, and transfer to the Zumo 660LM device with confidence that the routes are as planned.

Any help would be greatly appreciated

On my Mac, I have Garmin Express which allows me to load map updates into either of my Garmin vehicle-GPS units. I would ask Garmin customer support what your options might be at this point. I frankly do not know whether Garmin Express would support your device. Only they would know for sure.

You could also use VirtualBox, which is a Virtual Machine monitor that "runs on everything" ... free of charge, yet which is supported by none other than Oracle Corporation. (Yeah, the "humongous-database" people ... Larry Ellison and all of that ...) You could use this to install and run a licensed copy of Microsoft Windows with which to then run the legacy software.

And, unless Garmin has a rabbit in his hat that I don't know about, I would consider Windows-under-VirtualBox to be a perfectly acceptable and recommended solution in this case. (It is actually quite common ...) I use VirtualBox (on OS/X El Capitan, at the moment) to run several Linux VMs, and a couple of Windows VMs, and they all work flawlessly. (As you would well expect from Oracle.)

hello
Thank you very much for your input but I have a solution in mind for my needs.
Your input was greatly appreciated.

Great..how about posting it here, so others can benefit from your solution, then?
