New to the forums here. I just bought a 2006 X5 4.4. I am a junky with upgrades and stuff so I checked the nav first. Anyhow, I noticed that my software is 4-1/60. I purchased it on 9/13/05... so looks like the new ones are shipping with the v26 software? The display is really nice! I've never seen the old ones so I can't compare, but I've seen other nav units, and for OEM this one is pretty hot!
