MacGPS Pro - 8.1

I can't get MacGPS Pro to recognize my Venture Cx. Any ideas? Any work arounds?

I've used MacGPS Pro for quite a few years and watched it's capabilities grow along with that of the Macs on which it runs. Other mapping programs have come and mostly gone but Dr. James has always kept McGPS Pro up-to-date with the Mac OS and ever changing lines of GPS receivers. I go back a long way and can remember a time before there were personal computers and when my mapping was done on printed quadrangles. As time went on I purchased a Garmin 38 and some digitized quadrangles on CD from the USGS that I could view on my new Powerbook. Things didn't come together however until I purchased MacGPS and suddenly I could calibrate my quadrangles and view my Garmin's waypoints and tracks on these quads with my Pismo. I could even attach my Garmin to my laptop and display my moving position. I was hooked. Todays faster Macs allow MacGPS Pro to have even more powerful features such as tiling multiple quads or (as of the 7.6 update) tiling quads with different datums. You don't even have to calibrate your quadrangles anymore, with MacTopos you can have a complete set of calibrated quads for any U.S. state. There is talk now of new mobile Macs and I can't help but wonder if Dr. James will get MacGPS to run on these. Some reviewers have criticized MacGPS Pro for not adhering to Apple's "User Interface Guidelines" or for omitting certain features and while these concerns are often valid in my mind they pale in comparison to what MacGPSPro can do. I know of no other good alternative to MacGPS Pro on the Mac and few on Windows and so feel very fortunate that Dr. James has maintained it so well for so long. If you want to route a trip along America's highways get a TomTom or NuVi but if you want to see what's beyond those highways get MacGPS Pro.
