Well my RX-65 didn't last 18 hours before the first problem and this is a big one. No audio coming from the speaker and very low audio when I plug in headphones. Still starts up fine. Beltronics refuses to warranty it and they want $80 to fix it. Should I just accept the fact that it is broken and crush it or should I open it and see if it is the speaker or headphone jack that is broken and try to get it fixed elsewhere? My 78SE is back in the truck indefinitely and even if I fix this Beltronics unit, I already lost my trust in the brand and I don't plan on ever using one it in my truck again. Could this be an easy fix or should I just write it off?
