Help with replacement of SL70C MFD

[Mikeb365]

Hi Chuck,
Here is my electronics list:

SL70C MFD
Radome - 18" 2D
Auto Pilot - Smartpilot ST8001
Raystar GPS Receiver (120 0r 112 per book)
Suunto Compass (95 or 15 per book)

Your guidance would be greatly appreciated.

The reason I'm going through this is that my current MDF has locked-up. I've tried the tricks found in the forum to get it to restart but no luck. It will turn on then goes into a continual start-up loop and I can't turn it off. I have to turn off the power to the helm. My other thought is, if there aren't current MDF's available that will work with my Radome, Auto pilot & compass, what older units would use the same wiring as the SL70C. Also, if I were to send my current locked-up MDF in for repair, do you know how much this typically would cost. Just trying not to have to replace everything.

Thanks for your help.
