The Raymarine e125 has an internal GPS. It also has a ports for NMEA 2000, NMEA 0183, Ethernet and WiFi. You would need either a
TackTick T122 NMEA 0183 converter or a
Micro-Talk Wireless Gateway to have the TackTick instruments communicate via NMEA 2000 to the e125. With the built on WiFi on the display, you can mirror it on Android tablets and phones, and iPhones or iPads. The display can directly control Raymarine autopilots. I also had it interfaced with a Raymarine Radar.
This is a chartplotter and a whole lot more. It will overlay Laylines corrected for current on the geographical display when you have a course with Waypoints entered. (This is a Raymarine photo with the same software on another Raymarine display)

If you have a VHF radio with AIS, you can display AIS targets on the display. (this was on my boat)
