Yes you can, because there is also a Find button available, I do not know how close it will show how close the car is, but there is also a panic button on a fob, you can use that also. The worse case scenario you walk row by row on the parking lot till you find your car

 

Think we answered the question. US NX 450h+ customers do not get the horn option in the Lexus app for some reason.

 

I guess I'm guilty of trying to take this thread off-topic.. I was thinking the Horn is also related to the advance Climate Controls within the app. I was looking for Clarification that this also was one and the same. I would have (or should have) started a new thread but sometimes people think they are related and merge them. I thought perhaps I could put this to bed here, my apologies for taking your post off topic.

 

Hey Gamma742, when I said “I think we answered that question,” I meant that the silence after the question meant “no.” No US 450 owners have the horn app.

Didn’t meant to imply I was saying “we already answered your question dude!” Your input was helpful. Yes, the horn and extra climate controls seem to be linked for us US 450 owners. No extra climate controls means no horn either apparently. So weird. I hope that gets fixed in a new update. Who do we reach out to? For sure it’s not the dealer!

 

Cool product. Wish the NX horn sounded more like these!

 

Why my goodness , @oreon333 thank you so much, I had no idea you could do all those things to find a lost car.

YMMV,
