A:AnswerI wouldn't recommend this product for auto cd laser cleaning because I tried it in my Honda and it didn't work so now I'm looking for another product that will do the job.
A:AnswerIt should work. The disc has several delicate brushes that clean the laser reader, so I would think the nav system would have a similar laser set up to read the disc.
It looks way too simple to work, but it fixed my 3D BluRay player when it had a reader error. Good luck.
