What product specifically do you have with a u-Blox part in it? Provide product name and web page.

What are the electrical interface requirement of the RL70c? RS232?

Make sure you use the $GP Talker ID

Search the forum with "RL70" . I believe  there is already an answer for you.

The answers haven't changed from our previous responses in May.  Have you tried the Raymarine forum for insight?
Change UART output rate using UBX-CFH-PRT.
If u-blox product is M8 family, then use UBX-CFG-NMEA to ser to.old NMEA V2.0 version.
Refee to many other entries in this forum on how to use u-center to connect and  isuue these commands.  Your u-blox part should have flash memory so the chaged settings can be saved using UBX-CFG-CFG command.

thank you for your answers I am still not sure what the $GP Talker ID is? I bought the RS232 interface with D9 plug from ebay and was able to connect with success on Ucentre to change and save to gps transponder nmea 0183 the baud rate at 4800 and nmea to version 2 from ubx cfg prt the clock was working in the display tools so I knew it was working but when I connected the transponder to to the raymarine display RL70c the display still returned NO FIX. hope this helps you help me. steve

This is a forum for u-blox products. At this point, the forum resources have explained as much as possible about u-blox equipment and standard NMEA.  Your worst nightmare is that Raymarine may be expecting Raymarine proprietary messages as well (to prevent leakage of their GPS receiver market to third parties) or uses a more complex serial interface ( e.g. their high-speed bus, or high-speedbus two, or RS-485 signalling to support multiple devices on one common bus)

With no responses so far from u-blox forum members knowledgeable about Raymarine products, it is over to you to research the internet and Raymarine resources to find answers to your problem.

Yes, this will take some time and understanding.  Good luck with your project.  

Post your success to both the Raymarine forum and the u-blox forum.

You haven't identified anywhere what u-blox module you are using.  If u-blox 7 and earlier, the talker ID is $GP...
If M8 product, then talker ID can be $GP, $GN, $GL, $GB, etc. And most old charting and mapping software will accept only $GP.  Use CFG-NMEA to force talker ID to $GP.  Read the NMEA section carefully and repeatedly in the u-blox M8 Receiver Description and Protocol Specification document.
