I would love to see if anyone here can help me with an issue with my Acura TL 4th gen. Last week, during the snow storm my battery died out. My friend has a car charger and we tried to turn on the car with it. Unfortunately, we put the clamps in the wrong polarity. The battery fuse seems to be okay. We put a new battery and the car started, but the the navigation screen did not turned on and also the radio. In Addition, the remote control is not working. I replaced the battery on the fog, but that is not the issue. Car starts if I put the fob in the dash. What fuse would I need to check to restore the gps the radio and the fob?

Any help is highly appreciated.

 

Since you removed the battery, and apparently didn't use a device to maintain the car's memory, you will need to input the car's radio code. That should get the navi and radio back working. I don't know if that will fix the key fob issue.

If you don't have the radio code, you can look it up here:

I do have the codes, but that is not the issue the issue is that the GPS and Car Radio is not turning on. I am sure it's a fuse issue. I dont know which. Thanks for the reply tho.

 

To find out the power distribution, you need to at least know the year and package.

Best thing to do at this point is check every fuse and relay individually.

 

Here are all the fuses that control the radio.
Be sure to check not only the fuses, but also that power is supplied to them.

 

Yup it was Fuse 15 in the engine bay.

 

Thank you. It was fuse 15 in the engine bay.
