I have a 2014 ct200h, and it never had the navigation card from the time that I bought it used. I've been seeing them online some say that they're compatible with Toyota, others say they aren't. What do I look for when searching for a card? I know there are numbers on the card how do I know which ones are good for my car? Thank you,
Ian

Even if it were still there you might want to get an updated one.
Provide your VIN at a Lexus/Toyota dealer and get the latest one.

I was hoping to avoid the dealer. I find $250 for an SD card for navigation totally rediculous and refuse to pay it. I don't play the games dealers play.
I dont need navigation in the car as I love Google maps and Waze on my phone, I just thought it would be nice to have it working.

We pay $1000 for our phones and $100/month for service and the Dealers are playing games?...
Part of the fee goes to license the Data from the Map provider and
yes, $75/hour to insert the SD chip...Oh, I see what you mean!

I pay $50 a month for 2gb of data and unlimited calling across Canada. That includes my phone payment.
I found a place online that sells sd cards with the maps for $75 U.S. and they have very good reviews.

I'll use them instead of the dealer.

Yes, they have Lexus cards as well.

Sounds as if you are all set, I like to set the Waze voice and sound to "Play as a Bluetooth Phone Call"
and then she will prompt/trill over the speakers while I watch the Native Lexus Nav.

Note: you can use the fore/aft rocker button that is between the Map and Menu buttons to zoom the map.
Much easier than the old Garmin Style "+" and "-" buttons in the corner.
