hey guys, new here... i searched for this topic and found only one topic that discussed the cars actual speedo not working. everything else is about the speedo on the unit. so here goes.
i have an 08 hyundai tiburon.
i had a d3 installed today (done by a reputable local shop)
upon leaving, i noticed that my speedo wasn't working, so i turn around and bring it back. the guy who installed it checked the fuses, his connections, etc etc, but to no avail. he ended up calling hyundai tech but their only suggestion (sensor is disconnected) wasn't the problem.
i bought the unit on ebay used,
