Upgrading system

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tom,

Q1. System includes: Dual E90W, ST70 Autopilot, ST70 repeater, 4kw HD Radar, Raymarine, 240 VHF, DSM 300 Depth module, Raystar 125 Antenna, B260 Transducer. Can I upgrade to a E125 or ES125 and keep all my existing components?
A1. All of the items listed above (except for the second E90W MFD) may be retained for use with a system featuring a/c/e/eS/gS-Series MFDs. Please click here to view a FAQ addressing this subject. It is strongly recommended that all devices having a SeaTalkng communications interface (ex. ST70 AP Control Head, SPX Autopilot Course Computer, ST70 Multifunction Instrument Display) be updated with the latest available Raymarine product software updates to ensure compatibility and maximum performance of the system.

Q2. Secondly can I replace the ST70 Autopilot head with a P70R??
A2. While the answer to your question is quite likely yes, compatibility is dependent upon the model of autopilot course computer which has been interfaced to your present system. Please click here to view a FAQ addressing this subject.
