Just removed the GNS 430 and GTX 330 from the -8 and installed a GNX 375. I'm having a heck of a time getting the Horizon to receive serial data from the 375 - specifically GPS position on serial 5 and Traffic on serial 6. I have a guy coming by to help with port configuration next week, but thought I'd ask if there is a fundamental configuration conflict between the new Garmin and older GRT?
