[MJT95]

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!
