Traffic tie-ups can't always be prevented. But with Garmin's GTM 20 portable traffic receiver, you can often avoid them. Power your nüvi and get lifetime¹ traffic updates all with one cable.

5.0 out of 5 stars If your old one isn't working, December 5, 2009

This review is from: Garmin GTM 20 with Lifetime Traffic (Electronics)

I travel a lot , many rental cars etc.and carry my own GPS, Garmin770. Arrived at a new destination and plugged in my GPS and no power- I thought there was something wrong with the cigarette lighter outlet but noticed the "tip" of my GTM20 was missing. I went to Amazon and didn't feel like spending the $86 for a new GTM20, even though I like hearing the GPS lady warning me there is traffic in 2 miles. I was just going to buy a regular Garmin automobile power cord when I read a review of a guy who had an identical experience with losing the tip. He described in detail how he phoned Garmin support and got the replacement tip kit(fuse,metal and plastic screw in components)-I followed his direction and persisted in holding on for >30minutes but finally spoke to a human and ordered the kit for $11 including shipping and it arrived in 3 days. It assembled quickly and easily and I didn't have to by a new power adapter of any sort. I looked and can't find the review that gave me this valuable information but if you happen to need only the "tip" this review will save you money. I could not find this kit for sale on the Garmin website.

5.0 out of 5 stars Well worth the purchase, July 8, 2009

This review is from: Garmin GTM 20 with Lifetime Traffic (Electronics)

I have to deal with a daily work commute in excess of an hour each way, across LA county. I've generally tried to check traffic conditions on the web before I take off, but conditions invariably change as I'm on the road - more so given the long commute. The GTM 20 has made my commute times much shorter and more predicable now, and was the primary reason I bought my first GPS.

Initially I thought the unit wasn't working - the device has no LED status indicators on it (apparently the older models did) - so I thought I was missing a step in the setup. I eventually discovered that my house, which lies in the foot hills, is in the shadow of the FM traffic transmitters. However, once I'm a few miles from home, all is well.

As far as setup goes: there is no setup, no registration, no subscription to pay for - just plug it in. Very nice.

If you have long metropolitan commutes, I highly recommend the GTM 20.

Attractively priced and eminently functional. The included NAVTEQ subscription seems quite detailed, especially on local roads, and if used with the FM Clear Traffic subscription ($60 lifetime), which gives good coverage on the interstates, your traffic awareness is significantly enhanced.
