I purchased my 2012 Kia Soul with all the extras, my first brand new car in 25 years. The added features only work part of the time which is majorly disappointing.
I have complained several times and the dealer admitted there were problems and replaced the system, TWICE!
All my music was wiped out.
I've had the music go haywire while driving going between one song and another almost causing a wreck.
The sun roof sometimes won't open and the backup camera sometimes won't come on.
I was in a car accident that wasn't my fault and my blue tooth would NOT call 911!
After all repairs the system completely locked up and I could not make or receive calls.
All my favorite features are the ones that don't work!
Test your systems before you sell them to customers.
