Being that I'm old school and about to receive my Tucson Limited Hybrid the end of the month, how reliable are the infotainment systems on the Hyundai's and how many glitches have shown up that need to go back to the service dept? Do they go through updates like your home computer and if so, how do the updates get uploaded? Do you need WiFi from home or is all done through Hyundai's Blue-Link which I imagine you have to pay for after the first 3 years are up. What's the annual cost for this service and is it absolutely necessary to have? Will the GPS system still work without it? Lastly, do I need to take a college course to learn the intricacies of operation? If you have any other thoughts you would like to share I'm "listening". Thanks.
