The CD player on my '99 Cruiser is busted and I want to replace the factory headunit. The Crutchfield website says that there are no installation instructions or wiring harness available. Does someone know what year/vehicle model would be the most similar to mine so I could order instructions and a wiring harness? Also, any recommendations for a aftermarket headunit which would fit with the interior form and function of a '99 would be great. Pictures are definitely a plus. For those who have done it before how difficult will the installation be?
