JDM honda new cars ( like vezel ) come with internavi of 2 brands. Both offered by Honda Japan. One is their OEM and the other of Gathers Intervavi brand. Since these units are expensive, have japan maps in 3d and all the perks which are valuable there, many cars at auction can be seen without these navis, reason being they re auctioned/sold seperately over there. if you get a chance to look at the auction site, you'll find out that the cars without these actually get sold cheaper. Same was the case with my vezel which has Gathers vxm 155 top of the line model ( costs 217000 yen over there ), otherwise mine would've costed me at least 70-80k cheaper than what i paid ..
