I brought eon wth number pb 02 dc 9107, yet i have not received rc of my vehicle nor setero of car is doing work since i brought this product from goyal hundai jalandhar.
What the bloody hell going on. This is very rubbish, am really very very disappointed from the service of hundai, this is really shame for company that they are unable to provide a better stereo or music system in cars.
This is really shame
