The Round Port?

[Ricochet]

I see there's a circular port on the bottom of the ONE 3rd (between the reset button & mini-USB port). What's it for? Is there an automotive dock which attaches to it?

Thanks,

R?

I'm pretty sure you're looking at the port for TomTom's Real-Time Traffic receiver to plug into.

Is that where you would plug in the traffic antenna?

Well, it looks like an antenna cable. The cable has this blob of plastic on the cable that is the receiver. Beyond that receiver is the actual antenna. Technically that port in the bottom of the TomTom (showing 2-cars) is for RF input... or receiver output.

Here's a link to view a pdf with directions with small drawing:

Hope this helps.

Oh, right. The little cars confused me, but I get them now...
