How To Get Live Traffic And Weather Updates On 2013 Lexus Rx 350

The hot trend of topics lately is "my weather is not working, this car sucks". I've seen some odd statements like "Lexus hates Canada" and "the Canadian government forbids HD Radio". Got me wondering if it might be true and what exactly is our 3IS using to get Weather and Traffic.

Long story and google searches aside...

• TheLexus IS is the first car to offer free traffic and weather updates
• Think of the hardware as HD Radio (developed by iBiquity Digital Corporation) technology
• But the service is being runned by Clear Channel's Total Traffic HD Network (TTN)
• Like cell phones, TTN has coverage zones
• These coverage zones are still expanding
• If you're in a coverage zone you should see a HD logo on the Nav screen
• The 3IS can get data from both HD Radio as well as user's cell phone (if connected to Lexus Enform)
• If you are outside of an HD zone, your cell phone's data is used
• Default setting of the car should be to use "HD only" but you can select "HD & Cellular"
• You need the Lexus Enform app on your phone if you wish to use your phone for traffic/weather
• The Canadian government originally chose DAB but the system never matured
• Testing of HD Radio Data Services began again in Canada in 2013 because of automakers and device makers requesting it
• Traffic should update every 5 minutes (15min for non-nav equipped cars)
• Weather forecast should update every 60 minutes
• Weather Doppler should update every 10 minutes (60min for non-nav equipped cars)

My Weather and/or Traffic is not updating (it says "still downloading"!!!)

1. Look at the nav screen and see if the HD icon is there
2. If no HD icon, do you have the Lexus Enform app installed on your phone and is your car set to allow both HD Radio and Cellular data?
3. If yes to either of the first two than you might have an issue you should ask the dealer about it or you simply may have a weak signal to both HD Radio and your cell phone's data coverage. My phone constantly has spotty coverage at best, even in the same area with little to no movement. I personally would blame the coverage first before I blamed the car.
4. If no to both 1 or 2 than that is probably why you aren't seeing any updates. Give it time for coverage to return or you simply may be in a no/weak coverage zone.

While the system is brand new and there is bound to be some early adopter growing pains I think we are mostly seeing coverage zone issues. While cell phones are supposed to be the backup plan, I know I'm not alone in seeing cell phone data dropouts ...even in apps that only need to transfer bytes or only a few kilobytes worth of data. Would be nice to know how much data is being transferred not just so we know if its having a hard time transferring that much data to our phone but also so we know how hard our data plan will be be hit by.

I'm praying you guys found this useful because man, I'm wiped
