I recently got installed on the Boat with upgrade HD Transducer. In The Box was the Instalation Publications for the transducer and the Head unit with how to run the Power Cable ... Then a Pretty Color book Titled Helix SERIES OPERATIONS SUMMERY. This book is General for all the Helix units... Page 29 shows Chart View That is clear as mud when it comes to Navonics Micro card. and nothing to get Contours up on Maps.. then on page 30 the last sentence reads---- see your control head operations Manual --- Was there suppose to be one in the Box ----
