Upgrade from G5 to GI275 HSI?

[TimRF79]

All,
I got dual G5's; 430W, Century 2B with alt hold in my plane.
Wondering if the change from G5 HIS to Gi 275 HSI is simple plug n play or if there is more to it?

Also can the GI 275 provide GPSS?

Anyone has done this?

It is not even close to pug & play. There is no way I'd do it.


I could see adding a 275 to my dual G5s for an MFD or something but not at the price they want for them.
