Best Buy and Walmart have already released Black Friday fliers that show discounts on car audio products.
Walmart listed a Kenwood bundle with a CD receiver and 2 speakers at $88. The system includes a Kenwood PKG-MP18 CD Receiver with MP3 playback and a front AUX input. Speakers are 6-1/2″ round, coaxial, 2-way models. (Walmart is selling it in-stores only—not online. The offer may vary by region).
Best Buy is also offering an XM Onyx dock and play receiver with a car kit for $29, which usually sells for $79.
Of course, there are the usual specials on portable navigation devices, as well. At Best Buy a TomTom Start 50 GPS is listed at $69.99, a savings of $50 off the regular $119.99 price tag.
