I have a 2007 Honda Odyssey and it uses infrared 95KHz. I also have the orginal TV ears system which uses the same band. I have tested and the systems are interchangeable. Be careful of which version you get -- the newer one works on 2.3MHz and the TV Ears 10041 orginal works on infra-red. Assuming the montanavision works on the same setup something like this -- http://tinyurl.com/forgeraldren -- should do the trick.
I have a 2005 Pontiac Montana with wireless headphones for the DVD entertainment system. Can I use these headphones with the TV in my house? Is there a transmitter available?
