Hello, I purchased Garmin 60CSx from Advrider guy but he was using PC (window) and I got everything from him, but I am using Mac here. I just downloaded the Basecamp software for my Mac.. but I am wondering if 60CSx is compatible with the Basecamp or do I need to stay with MapSource?? Also, where can I find affordable 2012 map for the GPS? I kinda need one ASAP like maybe online downloading? Or is there a way I could get state by state for temporary fix because I am currently doing TAT on a very last minute plan on a very strict tight budget. My Mac and the GPS won't communicate at the moment BUT the guy who sold the GPS is currently with me and the GPS will still communicate with his PC (laptop). We are about to split in few days with me plan to go solo to finish the TAT because he plans to take few days break which is not within my budget to spend 4 nights of motel without TAT progress. Sorry for short notice but if you think you can help me on short notice, please PM me and I can give you contact info. Keep in mind I am deaf.. Thanks!!
