Two or three weeks ago, voice recognition stopped working on my 9-month-old 2021 Sonata Limited. When I pushed the speak button on the left of the steering wheel, I could not get voice directions, nor could I get voice on my nav system. The dealer checked it out and agreed to order a new radio head unit (about $3,200). On the internet I found that people who downloaded and updated their nav system with the April 2021 update (available for free on MyHyundai.com) solved this problem. I bought a 64GB scandisc card at Target, regular postage size, not the micro card, and downloaded the update to my computer (about 30-60 minutes for 31GB). Then I installed that download on the 64GB card (about 30 minutes). I put the card into a card reader and connected it to the USB port on the front console of the car, and with the car engine running, go to General, System, Update. It updated in about 30 minutes.
My new wide screen is now blue, and replaces the previous 3-section screen. Touch the small arrow on the right of the screen for a split screen showing 2/3 map and 1/3 either compass or radio or weather. (Swipe the 1/3 screen up or down to select the one you want).
I hope this info helps someone. Go to MyHyundai.com for more information, and good luck.

Thank you for your message. I am very frustrated that we lost our V.R. The dealer has "fixed" the problem twice - updated the computer software, etc. We also don't have working interior lights when opening the door; the "all unlock" when put in park is also sketchy and intermittent. Terribly disappointed in the service - wait for an appt; closed over the holidays. We just completed a 11 hour drive without being able to use the navigation system (no voice) AND, no hands free phone calling. This car has only 6000 miles on it. Sonata Hybrid... great mpgs - and comfortable but seriously have had it with the V.R. failures.

Mine does the same thing. Now the voice recognition wont connect. Sometimes the usb will play most times it wont. I had the dealer replace it once. It stopped working on my way home from the dealer. Its been out of commission now for 4 months, now they are ordering a head unit.

I just downloaded and install the November navigation system update yesterday (it took 1 & 1/2 hours) and it cured my voice recognition problem. I had taken my Sonata to the dealer and they poo-pooed the idea that it needed to be updated and instead ordered a new head which would take at least a month to get. I highly recommend anyone with voice recognition issues invest the time to install the update.
