Garmin TA20 (or TA10) Car Charger with built in antenna

Charge and power your compatible Garmin embedded traffic receiver nuvi sat nav with this genuine Garmin vehicle power cable. This cable has a built in antenna which is essential for digital reception if your nuvi has an embedded digital receiver for the Traffic Messaging Channel. Simply plug one end of the cable into your vehicles cigarette lighter connection and the other mini USB end (depending on model) either directly into the back of the nuvi sat nav or your nuvi suction cup mount cradle and you are ready to power and charge the device in-car.

The car charger will accept an input of between 10 volts and 24 volts, so it's ideal for use in both a car (which typically is 12 volt battery) and a truck or other large vehicle (which typically has a 24 volt battery).

IMPORTANT: For traffic information your compatible Garmin sat nav must include embedded traffic. This cable cannot provide traffic services to a Garmin model which does not already have embedded (built in) traffic services. If your Garmin sat nav does not feature embedded traffic capabilities and you require them, you will need to buy either the GTM 36 (FM reception) or GTM 70 (DAB reception) traffic receivers (pictured right) which both include a vehicle power cable.

To ascertain whether your Garmin nuvi model includes embedded traffic, please check the 'about' section in the menu of your Garmin nuvi sat nav. If it features embedded traffic it will say it has a 'built in traffic receiver'. You can then proceed and buy the TA20 vehicle power cable to provide traffic information.

What's the difference between the TA10 and TA20?

The TA10 has been superseded by the TA20. The basic difference is that the TA10 had a green LED light on the cigarette lighter adaptor, whereas the TA20 has a blue LED light on the cigarette lighter adaptor. Functionality wise the TA20 does exactly the same as the TA10, it's just the latest version of the cable.

What is the TA20 vehicle charger compatible with?

The Garmin TA20 vehicle power cable will provide POWER to any Garmin Camper, DriveSmart or nuvi sat nav but, for embedded Traffic reception, it is the ONLY cable to buy for the following Garmin sat navs:

Garmin Camper 660, 770, 780, DriveSmart 51, 50LMT-D, nuvi 2408, 2418, 2529, 2548, 2568, 2569, 2598, 2599, 52, 54, 62, 64.

Please note: Models above also include those ending in the following letters: LT,LMT, LMT-D - e.g. nuvi 2548LMT-D. If your nuvi model did not include the letter 'T' in its description then you may not have a built in (embedded) traffic receiver e.g. Garmin nuvi 52LM. If you buy this cable for a nuvi model which does not include a built in traffic receiver then it will only provide power to your nuvi. This cable cannot provide traffic services to a nuvi model which does not already have embedded (built in) traffic services.

What do the letters stand for? LT = Lifetime Traffic, LM = Lifetime Maps, LMT = Lifetime Maps and Lifetime Traffic, LMT-D = Lifetime Maps and Lifetime Traffic via the DAB (Digital Audio Broadcast) network. These letters signify what your original Garmin nuvi sat nav was supplied with.

IMPORTANT: For traffic information your compatible Garmin nuvi sat nav must include embedded traffic. If your Garmin sat nav does not feature embedded traffic capabilities and you require them, you will need to buy either the GTM 36 (FM reception) or GTM 70 (DAB reception) traffic receivers (pictured right) which both include a vehicle power cable.

To ascertain whether your Garmin nuvi model includes embedded traffic, please check the 'about' section in the menu of your Garmin nuvi sat nav. If it features embedded traffic it will say it has a built in traffic receiver. You can then proceed and buy the TA20 vehicle power cable to provide traffic information.

To enable the TA20 to work with your Garmin sat nav it may be that you will need to perform a free software update via Garmin Express at the garmin.com website. Garmin always recommend that you take free software and firmware updates. If you still experience compatibility issues Garmin recommend that you perform a master reset.

If your satnav is faulty: Please note that this TA20 is not supplied for the purpose of testing a faulty satnav.
If you are not sure whether this cable will do what you expect please supply your serial number before purchase.

The Consumer Contracts Regulations allows us to make a deduction from the reimbursement for loss of value of any goods supplied, if the loss is the result of unnecessary handling by you. You must handle the product, including the Garmin outer box and seal, no more than you might in a shop. For example: If the barrel of the cigarette lighter adapter is scratched or marked (from insertion into a vehicle cigarette lighter adapter), we will not accept the return of this product. It must be returned in factory fresh unused condition.

Rest assured that we have sold hundreds of these genuine boxed Garmin cables to satisfied customers. In the unlikely event that a new genuine Garmin TA20 proves to be faulty; the product will be exchanged without question.

Should you have any questions or queries prior to purchase, please contact us.

If your Garmin satnav has a built in (embedded) Traffic Receiver the TA20, with a built in antenna, will provide power and receive the radio signal for your built in Traffic Receiver. Otherwise the TA20 will act as a vehicle power cable only.

The TA20 will NOT provide traffic services to a Garmin satnav which does not already have a built in Traffic Receiver.

If your existing/previous cable was a TA10 AND YOU RECEIVED TRAFFIC INFORMATION WITH THAT CABLE then the TA20 will also provide the same service - but you may need to update your software or reset your satnav.

The onus is on you to know whether your satnav has an embedded Traffic Receiver.

It may be that the only way to confirm whether you need a TA20 for traffic services or whether you need a GTM36 (FM traffic services at £54.99) or a GTM 70 (DAB digital traffic services at £89.99) will be to advise us of your serial number. Garmin can then confirm whether your satnav came with an embedded/built in Traffic Receiver.

We don't supply cables for test purposes. For the return of an unwanted product the law only allows you to inspect a product as much as would reasonably be allowed in a retail shop. Break the seal, tear the bag, uncoil the factory packed cable, scratch the barrel inserting into your car cigarette lighter adaptor etc. - if the returned TA20 is marked or looks secondhand in any way; we won't be obliged to offer a refund.

We strongly recommend that you make every effort to know that the TA20 will do what you expect. No built in traffic receiver, out of date software = TA20 will act as vehicle power cable ONLY.

Faulty satnav = TA20 may not do anything and we will not take back a product that has been opened/used.
