Firstly the radio reception on my Griff Pioneer is excellent, I don't know why and I haven't investigated why, but when having the radio out, instead of the usual aerial connection there are a pair of speaker size wires to the plug and I don't know where they go and I'm not interested in finding out, maybe to an amplifier?
Anyway as I don't have a remote CD player either I installed one of these which uses the IP-BUS socket on the back of the radio.............

I can now play music from my phone via Bluetooth but I have to turn the wick up on the radio a lot higher which is fine unless I've asked for a TA etc and I get my ears blasted out.

I disconnected and the original FM antenna and fitted this powered dipole antenna from Halfords: https://www.halfords.com/motoring/car-accessories/... only £4 and I did a bit of work to optimise its position. I installed the Pioneer Smart Sync App, paired the phone with my SPH-20DAB head unit and I moved the FM antenna around using the signal strength meter on the phone radio display which helped place it. I also coiled up the excess antenna cable away from the antenna.

After a bit of experimentation I ended up with it mounted horizontally under the dash. I decided not to glue it to the dash cover as it would make dash removal even more of a hassle, so I stuck it to the back of the dash. Oddly the performance was better with the braided tail not connected to ground. The final position was about 4 inches to the right from its original position which changed 1 signal bar into 5 bars.

I then ran the DAB antenna to the passenger side of the dash and slid the little flexi di-pole under the leatherette trim below the windscreen with the little box tucked in the void for the ventilation vent. The self adhesive sticker was useless so I used the same 3M double sided tape that I used for the wing mirror glass:

I can get plenty of DAB stations and most importantly I can get Radio 4 and Planet Rock. The FM was not so great but miles better than before and I can now get all the BBC channels clearly.
