hello folks----strange situation with my receiver in e320---been working just fine for last 3 years--past week "phone" pops up in display"--never had a phone in car since i have owned car--and nothing works--cd doesn't play-radio doesn't work-weather band -nothing---stayed this way for 3 days and finally starts working again for 2 days and phone pops up in display again-- ANYONE ever had a similar thing happen??
