New Car Stereo System for iPod

My car is almost 10 years old and with that is a stereo system minus an mp3 port.  Sure I could try and mod the CD Player (you remember CD's, don't you?) to an input for my iPod.  But it might just be worth the extra $$$ to go for a new front end which has HD radio, GPS and etc., like the Kenwood DNX8120.  Have no idea on price, but their website gets into features here.
