Check the listing for details. TA-20 Power Cable/Traffic Antenna design for Garmin Nuvi GPS w/Built in Receiver. Condition: New. Listed at 23.85 USD. TA-20 Power Cord WILL NOT PROVIDE TRAFFIC for your GPS if the GPS does not have a "built-in traffic receiver"! PLEASE READ this before purchasing: [Garmin TA20 is a Power Cable with a Traffic Antenna and not a Traffic Receiver, there is a major difference!!] Not sure if you need a Traffic Antenna or Traffic Receiver? (Follow instruction below)To check your Garmin Nuvi to see if it has the built-in traffic receiver or not.From the Main Menu > Settings > scroll down to Device > About.Look for "Built in traffic receiver? Yes or No."If, No, or if you don't find this statement, your gps does not have a built-in traffic receiver, the GTM 36 or GTM 60 traffic receivers would be required to receive traffic information if the GPS in compatible for traffic.Also note Garmin's [-S] model GPS units use your smartphone for traffic or GTM60 if you don't want to use your cellular data. NOTE: The letters LT, LM, or LMT on the GPS label only stand for L-Lifetime, T-Traffic, and M-Maps so if your unit only has for example 2639, you can select 2639LMT (Keep in mind, this may only work as a power cord on some LMT models as some require a traffic receiver like the GTM36 or GTM60). Feel free to ask questions as Garmin's traffic units are very confusing! For a Traffic Receiver as in photo below, GTM 36 Traffic Receiver or GTM60 Traffic Receiver
