I’ve been wanting to upgrade the audio system in the van for some time so I could have Apple Car Play, DAB radio and better connectivity. I wanted the new system to be flush in the dashboard so after some research I found a Pioneer system sold by Dynamic Sounds.
This is quite a comprehensive upgrade. It is not particularly difficult, it is time consuming and you need confidence to cut out internal components of the dashboard to make room for the larger unit, relocate the Fiat Blue & Me module and make space for the wiring harness.
I believe you also need a multi-tool to be able to cut accurately in confined spaces.
