KBSound ISelect 5'' 2012 - Audio Input Options for Raspberry Pi Connection

Does anyone have any knowledge whether it is possible to connect an audio signal from a raspberry pi to a KBSound ISelect 5' radio (purchased in 2012, without Bluetooth module)? Unfortunately I can't find any information on whether the head unit has any audio input (e.g. jack or coaxial), and at the moment I don't have access to it. I'd like to know the possibilities before I start stripping the ceiling to get to the radio (unfortunately the team setting up the place placed the radio in a rather impractical way).

No, the only option for connecting an additional audio source is a dedicated BT module.

Ok, there are BT modules on the market for around 370pln. Do they work with every version of the I select 5 radio or only the new versions where there is a BT sign on the remote control?

Bluetooth module only works with new type radios, before purchasing the module itself, check that there is a Bluetooth logo on your radio.

- information found on the Distributor's website.

Well, I can see that the hardware is dire, as there is still the option to connect to an Ipod docking station, but these cost over £800 each, given that it fits at most an Iphone 4, it's a waste of money.

Would it be possible to use the remote control and the speakers by connecting it to an amplifier? Then you could somehow coolly add a light sensor diode as a switch. The question is how much would such an amplifier cost to connect the speakers to? It would be even better if it had a powered USB output to power the Raspberry Pi directly from it. I'm just looking for a cheap solution for having a mobile managed Spotify, but using the speakers in the ceiling rather than a free standing BT speaker, as I don't have room for that in the bathroom anymore.

16Ohm speakers, 2x1.5W built-in amplifier - you could be tempted to add an IR receiver to the RPi, plus some sort of low voltage amplifier circuit....
