"FREE" Titan III GPS Antenna. Just Pay postage April 07, 2012, 10:20:55 am Yahoo Message Number: 129701I have an almost new Titan III GPS Antenna. Purchased 2010 ?? http://www.amazon.com/GPS-Outfitters-Titan-Universal-Antenna/dp/B0000ATIUGI use it on my Garmin Street Pilot III. As the amazon ad says Connects to most GPS receivers with external antenna jacks. Note: most newer GPS units do not have ext antenna jacks. My new Garmin doesn't have one and doesn't need one. It works fine even under the overhead cab. This is for older units.FREE. You pay postage.Cheers Ed As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.
