For Mac users
there is a conversion process as well as tools available from Garmin which enables you to convert maps to Mac format. To view these maps on your Mac you also require Bobcat which is a similar application to MapSource but developed for Mac OS. Refer to Garmin’s web page
for more information on this topic. From here links are provided to the tools you require for the conversion process.
T4A GPS Maps are available in Mac format to registered users of version 8.02. Please contact email@example.com
