To answer some your questions, we have a different firmware for both of these devices since they have different features. In other words, they are not identical products.
As of now, for the GB-580P, you're able to create Routes from the unit itself by going to Main Menu > Navigation > Routes > Create New. For more details, please refer to its User Manual (http://www.usglobalsat.com/store/download/678/gb580_user_manual.pdf
) starting from page 29.
The route planning feature is not currently supported in the Training Gym Pro (the program used for this device). However, our engineers will look into this and see if they can add this feature.
The GB-580P is using a 2.4G ANT wireless HRM, as stated here: (http://www.gs-sport.com/products.php?en_product_id=10
). To learn more about ANT, please click here: http://www.thisisant.com/
The Timex Cycle Trainer 2.0 can be used with TrainingPeaks software, which is a very professional program. You can learn more about this software online or just click here: (http://home.trainingpeaks.com/
). As for the GB-580P, currently, we don't have any MAC OSX software available. However, we would have the Cloud version of the Training Gym Pro. For more info, please refer to this forum posting: http://www.usglobalsat.com/forum/index.php?topic=4257.0
