So, Im placing something into My X5 and up until now, I've been focusing on the Z1 (got BT, IPOD, NAVTRAF, PAC controls,etc. all for the Z1). Well, after seeing this push of the D3, I'm a bit skeptical on going to the Z1/Z2, especially when i hear about so much improvement over all other (American) AVIC models by the D3.
Any input, compare - contrast, etc?
