I haven't driven the wife's car in a few weeks. Today I get in and hear what sounds like a K-band alert, but the RD isn't displaying anything???
Look around and notice a solid red led on the ZR4...rear head fault. The system just turned 3 years old so I decided to have a look at the head and this is what I found..... One of the reasons I went with the ZR stuff was dependability too.
