Question about 2009 Hyundai Sonata

1 Answer

Where is the radio speed sensor wire on Hyundai/Infinity model 96560-0A500 radio?

I recently replaced the factory Hyundai/Infinity AM/FM/DVD/GPS unit, model 96560-0A500 after the operating system became corrupted. I cannot find wiring diagrams for the harnesses specific to this unit - and there are a LOT of wires! Can someone point me to the wiring diagrams or at least where the speed sensor wire is located? There are 3 main connections - a gray 8-pin connector, brown 8-pin connector and an interconnecting yellow/green/blue 21-pin connector. The antenna connection is also not standard and I'm not sure which of the 2 black wires are for AM/FM or if they are both required. Thanks!

Testimonial: "Thanks Jerome. I was told it was the yellow wire on the gray harness connecting to the radio (pin 1). I had it on the blue wire across from it. After relocating to the correct wire and soldering it, the speed is now functioning on the new GPS radio. Thanks again for the reponse!"

SOURCE: Need help with 2004 Hyundai Santa Fe Audio Wiring

Sounds like you need a light tester. I would guess that at least 8 of the wires are speaker + & - the others will be Main power and earth Possibly electric ariel, Memory store and a wire for the anti theft circuit. Assuming the stereo is factory. Any Audio shop can perform a test to clarify the purpose of the wires Wouldnt worry about the blank its probably a position for a newer or different model to yours.

I may be able to figure it out but with the haynes not showing the codes which they will usually show the options for all models,I am not sure but will try.If you have a more basic model,not "loaded",the gray/black wire could be for a more loaded model which has a motor driven hatchback so I would like to know if yours is or not.Manufacturers commonly make a 'universal' wire harness,but depending on the model may not use it.You may have also seen it in fuse boxes where there are empty slots because the system they are for is not on your car.
The green orange may be the return for the first wire.If there is any way you could send me a picture of the diagram it would be helpful.There are a couple ways to do it without taking out the page.If you have a digital camera,take somewhat close-up pictures,at least so I can read the letters,maybe 4 or 6 sections,or just the particular section you are referring to.You can use a cell phone,it will be a little tougher,but you can TEXT the images to my email.Either way it is gmccarthy 86 hotmail com.If you are in the USA and want to chat,let me know and I'll send you my # as I do not have free long distance,hopefully you do.Good luck! Greg I'll be here all night EST.

How to replace antenna jack 2012 Hyundai accent?

Just to confirm this is the antenna wire connection at the back of the factory radio? IF that is the case then you can remove the radio and take it apart and work on it. You can also get a new unit on ebay etc.

My Saturn factory AM/FM radio on my 1996 SL gets some FM reception but no AM reception. I am trying to determine whether I need to repair the antenna or the radio.

You will need to pull the radio out of the dash and make sure the antenna is still pluged into the unit. If the antenna is in the windshield make sure the glass is not broken, and the wire broken. If there is an external antenn, you need to check the connection at the bottom of the antenna, and the wire is good between the antenna and the radio. Has any new items been mounted recently, the screws could have damaged the coax.

How to connect a Hyundai car radio to my Toyota ute

This is most likely impossible if either is a late model vehicle. As far as wiring you will need to cut the factory Radio harness out of the Hyundai, you will also need a wire diagram for the Hyundai. You will need to buy a harness designed to install an aftermarket head unit into the Toyota, the new harness will come with a description of which wires perform what function. You will then need to match these to the wires on the harness cut from the Hyundai using the diagram. Even if you do all this other hyundai radio will not bolt in where the factory Toyota radio was, and there is no adapter made for something like this. I would suggest just buying an aftermarket stereo. It will be MUCH easier and will almost definitely sound better than a stock Hyundai unit.

I own a 2001 Hyundai Elantra and I can't seem to reach a speed over 55 without immense trouble. It also pops when idling. I have replaced the spark plug wires, transmission speed sensor, and cats are fine....

im assuming that you also have a check engine light on. first have that scanned. it sounds like a knock sensor keeping the timing retarded. was the timing belt replaced recently? if it wasnt mechanically timed properly, it would cause this. has the fuel system been checked for adequate pressure and volumn?

XM is better than AM. Much worse than FM.
