update for any one interested in my Audio upgrade....
Last weekend I installed the new Sony Hi-RES speakers.... replacing 500Q OEMAudio+ setup. It served me really well and I thank OEM+ for all the support over the years. 2020 took out AUX connection so I could no longer connect my external hi-res DAC via AUX to play via OEM+. Found a local buyer for the OEM+ system.
so here is what I bought ... some of this is still in the mail so I will be completing the install over several upcoming weekends. Will try to capture some pictures.
