Garmin MapSource is computer software that is included when you purchase a Garmin map product on DVD or CD. You can plan and organize trips with Garmin MapSource.

Garmin MapSource Features
By default, you cannot install Garmin MapSource without existing MapSource product. But there is a hack to ‘trick’ the Garmin MapSource installer, and let you install it even without existing Garmin MapSource installed.
How to install Garmin MapSource without existing MapSource?
You need to have Garmin Training Center software. Of course, you require Garmin MapSource software too. Download both of them.
Garmin Training Center software – link
Garmin MapSource software – link
Install Garmin Training Center software first, and then install Garmin MapSource software. Garmin MapSource installer will not prompt that you don’t have existing Garmin MapSource anymore.

I downloaded the two links above and loaded/installed “Training Center” first as stated and then loaded/installed MapSource… or tried to, and got the message “Previous MapSource not found! Setup will terminate.
SO? Why won’t it work?
I’m trying to plan some routes and was told that I needed to use MapSource to do it for the trip.
Someone get back to me ASAP…Thanks, like today?
Maybe Garmin fixed the bug so you can’t install it without previous version…
