Walt,
Thanks for the information.  We will definately research and look into this further as we are always looking to add and improve the feature set of the iFly GPS.  I have listed this on our wish-list in conjunction with others like the AOPA Facility Directory.  I will make a contact to Pilot's Guide to inquire about availability and pricing options.  Thanks again for your great feedback.
If there are any questions I can help you with pertaining to a purchase, please let me know.  Feel free to contact us at 888-200-5129.  Keep in mind we are offering "FREE SHIPPING" for the Holidays.  We can still ship one out this week.  Have a Merry Christmas and a Happy New Year!
