So i passed my beloved 172 cup to my wife and bought a 197, first impressions i love it, not as raw as the 172 but i love the extra head room when pushing it hard. anyway, back to subject =pHaving had a full set of JBL speakers and pioneer HU in the cup, going to the standard set up in the 197 has been horrible. Ive just ordered the Alpine HU mentioned above with a pair of JBL 16.5cm components for the front. Ive also ordered the megane II fascia adapter. Now im sure when i installed the pioneer into the Cup i needed an iso wiring adapter of some sort, but i cant for the life of me figure out if i need one for the above combo. I think i need the CTSRN005 + alpine patch lead for the steering stalk, ill get that later, just wondering about the iso adapter, any ideas?
