SV-GPS-250 plus SV-GPS-2020?

[DHeal]

I built/fly a SV 1000 (and AP/ADSB/SV-GPS-250) system in my 3-year-old RV-12 ELSA (Very happy with it!). Soon I will be purchasing your SV-GPS-2020 to enable 2020 compliance. Can I install the new SV-GPS-2020 puck physically right next to the existing SV-GPS-250 puck (i.e., any radio signal interference issues)? How would the two pucks be wired to the SV? Once installed, would I set my new SV-GPS-2020 as the primary HSI nav and the old SV-GPS-250 as a secondary HSI nav -- how would this be done? Is there any advantage to having both the SV-GPS-250 plus SV-GPS-2020 installed? Thanks!

Please check out section 8 of our install guide, which covers all these questions, particularly page 8-6 which covers converting from a 250 to a 2020.

You can install both antennas (I did in my RV-7A). If you have two screens, you will need to wire both antennas to both screens.

I asked a few months back if it was ok to splice the power and ground from each screen to both GPS pucks (the manual contradicts itself here) and have not yet received a final answer. If you don't have dual screens, this is not a problem for you.
