A third major trend in automotive electronics is the ongoing development of greater comfort, convenience and connection to the world outside the vehicle, going back to the earliest installation of car radios.
我的問題是上面最後這句「going back to the earliest installation of car radios.」
能否請高手指點一下，謝謝！
祝大家新年快樂！
以下這段是接續的內容，可供參考。
With increased freedom from the strains of driving, consumers will want their traveling experience to be more enjoyable in terms of climate control, sound, light, communications, and at-hand or voice-activated conveniences.

是在修飾前一句connection outside vehicle. 意思是最早人們開始在汽車裡安裝收音機就是要在開車的時候也能跟外界有連結，意指現在科技把駕駛經驗做的好像你在家一樣， 有電視， 有高級音響， 有冰箱 ， 這些就是文中的外界連結

感謝詳細說明，了解意思了，我再想想這句的中文要怎麼翻譯比較好，如果可以的話，也請不吝指教，謝謝！
