I am about to purchase a 1815 radar package and am wondering if my standard horizion chartplotter will provide the correct heading input so I can use the tracking info of targets. ( course and speed, cpa, tcpa of targets). My chartplotter has output nema 0183 sentences of GLL VTG BWC WCV APA APB HDG BOD XTE RMA RMB RMC GGA HSC DBT DPT MTW VHW GSA GSV. Thanks for your response
 
Let me ask another question. Will my chartplotter input work to receive cpa or will I need to purchase a pg700. Also my autopilot (comnav 1420) has a nema 0183 hdg output from the compass but only at 1per second update rate. Will this work?
