ProNav

[MJT1995]

I am looking to upgrade my M135i LCl to pronav shortly, it has the following: NBT Entry nav small screen with gps. 

I found a touch screen, HU and controller with the following part numbers, 8721882, 8709339 and 9866964 and I was wondering how I could find out if it’s compatible to code to my car? 

The HU hasn’t got a GPS port but would I even need a gps HU as i’ve never used the built in gps. 

Appreciate your help!

It should be compatible. You would have to do some wiring to fit the headunit but some can work without any modification.
If you need to activate features like map , craplay you will have to wire the oabr correctly and patch the unit.
