In regards to the warranty- unlike others, we are quite liberal. As mentioned above, its doubtful a unit sits on the shelf for some time, but it occasionally does happen. If you have proof of purchase, but no warranty card- that works too. Because of the serial number system that we use, we can see when it left here, which dealer it went to, and in some cases- when that dealer sold the unit. Even if you have no sales information, we can still get a rough idea of when you purchased it. With all of that said- we will work with you. If you were to have a problem outside of the warranty or a problem that was caused by the install or something like that- our repair costs are quite reasonable (read: not a money maker for us- we do good to break even on a repair).
