For what it's worth...199L was down for maintenance while I was visiting the
factory. They had the glare shield pulled off, so I noticed that they have a
GPS antenna mounted at the top of the stack., just underneath the glare
shield. The Legacy has great access to the back of the panel, so I thought
the placement made sense. In addition, the leads for the antenna are
shorter.
