Help organizing shopping list and sequence

I am planning a total upgrade to my electronics systems and would like to do it over a couple years. Here is my current inventory:

C80 Classic MFD
ST290 Speed/Depth
ST7001+ Auto pilot
SL72 Radar
Ray 215 VHF
HD 250 DSM

My thought was to start with my VHF this season. Then next season replace the MFD. The following year I would replace the radar and/or auto-pilot. I had the Evolution on my last boat and loved it.

Can you recommend the best replacement for my VHF?

Also, my helm is constrained to a MFD having the roughly the same overall size as the C80 classic. What would you recommend there?

Does my order of replacement make sense?

Thanks

Dave
