I just got my 2011 Elantra and was interested in upgrading the headlights to an HID setup. I saw in the manual a specific reference to aftermarket HIDs might cause problems with the Elantra's audio and electronic system (page 4-98 of the manual). Has anyone upgraded their Elantra to HID successfully or did you have audio and / or electronic problems? I don't want to spend the money on the HID if their is going to be a problem. Thanks for your input.
