so my z1,2,3 was stolen it had all the upgrades and loved it. but i figured the z140bh being the newest and most expensive unit they make it would be 100 times better but so far the navi blows, the city view only works in a few cities and not mine and im in a big city. they did away with the speed gauge cluster screen and added an eco chart screen looks cool but i have an audi RS4 what am i gonna do with a eco chart i burn more fule idling for 10 min than most cars burn in 100mi lol. the radio is awesome you can run hd and regular at the same time or seperate the xm seems better u can tag song
