There's a lever that connects the driver-side rear shock to the Automatic Level Control module (the air compressor and the ride-height sensor). Disconnect the lever from the shock and rotate it up and hold it. The compressor should kick in when you hold in place after a few seconds. If it doesn't kick in, make sure your fuses and relays are good. Otherwise, you may have a failed ALC module/burned out air compressor (from the shocks being shot). After you replace the shocks (and after you recouped from the heart attack you had when you shelled out $500+ for each shock), replace the ALC module/compressor (it's all one unit), and test it - it should kick on when you rotate the lever up again.
Figure about $350 for the ALC module from your dealer, and make sure the part numbers match! Your truck came with an upgraded ALC module from the 2001-2004 module, which were prone to water damage.

I have not seen this personally but it has been brought up enough to suggest using an after-market portable (that is, if the problem is not in the headunit>portable interface).
Sadly, I do not have the data to tell you if that is the case or not but an aftermarket portable might be a good resolve if you are willing and provided that you can hook it up to the Yukon system.
Try talking to a Rep at www.crutchfield.com to see about compatibility of some after-market portable players.

I shipped my 2006 Yukon Denali from USA to Saudi Arabia. When I to purchase the Middle East map DVD for the navigation system. GM Navigation answered me that they do not have the middle east DVD and I should contact the European branch. The dealer in Saudi Arabia is asking for $1200 for the disc and I know it is worth no more than $400. Could you please direct me to someone who sells the 06 Denali navigation map DVD? Thanks..
