Rostra seems to be the latest name for the same or mildly-updated unit, as thier    installation manual appears to be pretty much the same unit, installation procedures and features.
  I love my Audiovox unit (purchased on ebay),that' s installed into my '87 automatic Westy.

  Yes.  Check the archives from about two weeks ago, full discussion.  You're
  looking for an Audiovox CCS100, NLA from the stores but can be found on
  eBay.  But, the price is going way up, over $200 for the complete kit, used
  to sell in the stores for $105.

  There are other kits on the market from Rostra that should work but I know
  nothing about them
