I assume you mean a bluetooth device. In short, it's not easy. There's no "sure just go buy this thing on Amazon" kind of solution. It can be done but you need a copy of the schematic, some electronics skills and an understanding of how the jukebox sound system works.
The input of the stock amp is expecting a magnetic phono cartridge level, not really line-level from a bluetooth device. It's close, but the EQ on magnetic phono inputs is not flat, and the level is lower. So you'd need something that converts line level to magnetic phono level (is there even such a thing). Then there's the juke's muting circuit, which keeps the amp quiet when a record isn't playing. You can remove the mute plug from the amp to defeat it temporarily, but you'd have to do that every time you want to use it for Bluetooth, and keep putting it back when you're done. All that plugging and unplugging for something that's not designed to take that kind of punishment would make me nervous, so you'd really need to rig up a switch.
Or you can replace the entire amp with a bluetooth-enabled amp, hack into the wiring, and connect the amp to the juke's speakers. I've done this before; if you understand electronics and can work with wiring it's not super difficult. Rowe-AMI jukes use a common speaker ground though, and most modern amps don't like that, so you have to rewire it a bit to split those grounds out. You will also need an external phono preamp to keep the jukebox side working, and you'll need to make your own muting circuit or it'll sit there making noise from the tonearm all the time. All doable, but it takes time and understanding.
Sorry, no magic bullet here.

I have one of those accessory boards. Just missing the microphone cable, not sure if that is needed. PM me if interested.

Hi Darren,
Which "accessory boards" do you have--- for which amp ? Mic cable was never included as a part of it.

Hi,can the accessory board 60792702 be used on the 125 watt amp on a r92? I just picked one up and found this accessory board for sale for a pretty reasonable price. My only issue is it doesn't seem to come with wiring harnesses. Anyone have any clue where I could find these? Much appreciated!

Hi Pat,
The "accessory boards" were all very similar--but slightly different-- If you have a correct schematic for your R-92, and it shows that board, I wood ASSUME, it would be an easy modification, if it is not already correct. MOST of the differences, I know of are in the plug, on the wiring harness, it looks like you will need to fabricate, anyway---- Ron Rich
