The HCE-100XM delivers XM's NavTraffic service to your compatible Alpine navigation system subscribe to it, and you'll receive continuous updates on traffic conditions along the programmed routes you drive.
While your navigation system guides you, NavTraffic keeps an eye on accidents, lane closures, and delays along your route, and warns you in time to make adjustments. It'll also let you know if there are any scheduled traffic incidents, like traffic diversions, sporting events, road construction, and more. In some areas, it even informs you of the speed of traffic flow on the roads ahead.
You'll need to be sure and pick up a roof-mount XM antenna to receive the signal. The HCE-100XM only picks up the NavTraffic service. If you'd like to subscribe to XM Satellite Radio, too, you'll need a separate XM radio (not included), which you can connect to the HCE-100XM's antenna output.
Please note: the required NavTraffic subscription costs $9.99 per month. If you have the additional XM radio, you can subscribe to XM for $12.95 per month, plus $3.99 per month for NavTraffic. XM service is available only in the lower 48 states, not available in Alaska, Hawaii, or U.S. territories.
NavTraffic is currently available in most major metropolitan areas.
