Im new to the forum and this is my first post. I drive a stock (black on black) 2015 IS350 F-Sport. Within the first month of ownership the battery needed replacement. I installed the new battery and when I started the car the display screen remained black. Nothing I tried would turn it on and I looked for a fuse and was unable to find one. I looked under the hood and under the drivers side dash...I reviewed the owners manual and still found nothing relevant. When I press the remote touch **** I hear the "ding" and it moves to the zero baseline when I start the car so it appears to be just the display thats not working. Can anyone help with this issue before I take it to a mechanic?

Thanks for helping me out!

 

Good Afternoon!

I just went through the same process on my 2014 IS350. Had the original Lexus battery. Had it only a month. After removing the 520 CCA battery, Went to Walmart and installed a 700 CCA MAXX battery. The car started immediately. The radio Reboots taking about 1 minute while reading from the SD card. Try turning off the entire vehicle. Remove the SD card. Then start the radio. When the radio ask for the SD card, reinsert the card and allow it to boot properly. Hopefully this works. Good Luck.
