Having lived with my new Android unit for a few weeks now I am still very happy with the overall benefits but have only one reservation

The GPS now works flawlessly after connecting to the original antenna with an adaptor (blue Fakra) so there is no need for the supplied antenna

However the FM radio reception is definitely not as good as the original (Diversity) system and only the strongest stations are really clear so I have come to the conclusion that a conventional antenna is necessary
Also the DAB receiver that I also fitted has really terrible reception so the same applies

I am now looking for a suitable FM/DAB 'bee sting' or 'shark fin' antenna which I will mount on the roof - has anyone had the same experience?

 

Fitting a cheap 'bee sting' antenna has made an astounding difference! I chose an FM/DAB antenna and immediately I noticed a huge improvement in FM reception and the DAB is now flawless (and a big improvement over FM)
Installation is a bit of a pain, drilling a hole in the roof and routing the cables through the headlining and down the A pillar, then across to the head unit. Definitely worth it though and I would recommend that anyone fitting an Android head unit does the same thing.

I am now going to plumb in the USB socket in the armrest so I can charge my phone while driving and use USB sticks rather than SD cards for my music. Then I want to upgrade the unit to Android 9.0 and I will be content
