Okay so im confused and hoping for some help here, i bought my e53 a year ago now and i love it!!! 🤗 I am now wanting to put in the retrofit monitor headunit. To which i have got one on its way now. I have been told that nothing is going to work on it unless i have the wiring loom and the navi boot part. Now i know that i can watch tv, cant use the nav until them parts are bought. So does that mean that the radio will not work either?! Im hoping is going to plug and play into the designated slot on the dashboard.

Many thanks

The newbie
