PAPAGO GoSafe 738 後視鏡行車紀錄器 使用心得

我的Honda Fit本來就裝有一台Vico DS2   但由於前些日子上武嶺時吸盤可能因為大氣壓力變小的關係而脫落, 讓我稍稍起了換行車紀錄器的念頭
又好巧不巧家人的行車紀錄器壞了一台...

其實早知道Costco有賣Papago這款後視鏡型的行車紀錄器  跟網路上比價也確實是便宜不少
還送一張16G UHS-I的micro SDHC卡  整個很划算

2013 瑞法行 :: 瑞士首都 - 伯恩 Bern

其實在到達伯恩之前根本也不知道這裡的故事與特色景點
只知道他是在蘇黎世到日內瓦的中間
於是這次的瑞法行第一站就選定為 -- 瑞士首都

三個沒做什麼功課的人從蘇黎世搭火車到伯恩, 出了車站完全搞不清楚要往哪走
原來是我們提早從Schanzenstrasse這條街的出口出來, 以致出口不是在火車站的建築物內

問了一下路, 找回火車站正門口, 站內有置物櫃, 先去遊客服務中心問看看一日遊該怎麼走
