Roof mounted DAB aerial installation
 

In view of the wide variety of DAB radio stations now available compared to FM, I am considering installing a roof mounted DAB aerial on my 75 tourer. This is the aerial I am looking at: https://www.caraudio4less.co.uk/kine...na-p-2422.html.

I have made a few assumptions regarding the fitting and any comments are welcome.

I plan to drill a hole above the interior light positioned above the rear seats as this looks like it should be far enough forward that the tailgate does not foul the mast when open.

I then plan to route the wires down the passenger side of the headlining and down the passenger side A pillar, behind the glove box into the centre console.

One aspect I have no idea about is the power supply for the aerial. Could I split the power supply to the existing aerial in the glass mounted in the driver's side rear window? I assume there is a wire that runs along the drivers side of the headlining. I would prefer a solution that allows the original VDO CD tuner to be reinstated once the car moves on.

I would have thought that the interior light you intend to mount above will have a live feed to it i assume, but elecktrickery is not my foray :shrug:

I fitted the shark fin version recently and it is a switched live you need so as not to drain the battery, i actually ran the power wire into the boot and found a switched live there, i think it was part of the reverse sensors wiring i used. I used a multimeter to find a suitable wire.
I had thought that i could tap into the factory fm/am module in the c pillar for 12v switched but didnt get anything from it on testing so assume it was isolated when the headunit etc was changed prior to my ownership.

Disregard the above, it actually created a fault on one of the sensors, once I removed the extra wiring all was good.
So, I thought I would try the boot light live but that of course only works when interior lights are on...did prove the amplifier works well at least.
So now I am in same boat, I have a wire in the boot area looking for a switched 12v live, if anyone can help.
Mine is a highline but that part was removed prior to my ownership and now have an Xtrons fitted
