I just recently purchased a 2013 Nissan Altima SL with the tech package. I found out the hard way, that voice adaptation is not available. This makes the bluetooth system useless to me. Without the unit knowing my voice, it cannot interpret names that I call. I have been to three dealers as well as contacted the regional office for my location about this situation. Here is the best part, after Nissan has spent some time trying to figure out the problem, they reconized that the unit does not have this feature and they are not going to replace the NAV unit with a unit from a different vendor that has this option. Nissan does not think it is an important feature for the comsumer to have despite having VR (voice recognition) which may work propertly from time to time, not to mention, having a tech package that is now useless. Though the lower SV model has the Voice adaptation installed. Go figure that one out.
