I have an older non functioning radar on my boat I purchased several years ago. I have just purchased a Garmin MFD as my primary and would like to get my furuno going. I only have clearance for the 3.5’ / 41” open array. The new model set up fits that but it is just out of my budget so am looking at the older ones. Max Marine has some refurbished models for around $1500.00. My question is which model was the last produced and most advanced in that series ? Looks like most had the RDP - 149 VX2 but there maybe a better MFD that will work with this older layout. This is going to be my back up system with GPS and charts as well. Thank you for your thoughts.
