Replacment aerial.

[The vest]

Hi I have a 2016 st d23. My Arial has snapped and I need to replace it. I wanted to put one with a built in booster built in and possibly DAB capabilities ( for future use).
I have heard that the GPS Arial is in the top radio as well is this true amd how hard is it to get the cables down to my head unit.

Sorry if this sort of thing has been asked before I couldn't find anything.
Thanks in advance.

The same thing happened to me ,when i first got my NP300 backed into the garage and the aerial got caught in the garage door, i managed to pick one up complete for $40
