Program to convert KML or GPX to IMG (Garmin)

Hey Guys... Sorry for the first post, my customer really need is the IMG file. We need a KML or GPX(whatever) to IMG (Garmim) converter.. Need the source code. Cannot have any watermarks. Can use another tools if is opensource or freeware, but in transparent mode to the user, ie, the end user may not be aware that other tools are being used. That program can be coded .NET or VB6 or Java. The program will run on default account on windows, NOT ADMINISTRATOR, we don't have right to install nothing who need admin acess. Sample files (input) to convert to IMG. KML Sample: [login to view URL] GPX Sample: [login to view URL]
