I just recently purchased a replacement disk for my navigation system. I purchased the car used and it hadn't had one in it since I purchased the car.

When I first started using the disk, everything seemed fine, but after a few weeks the system started to 'detiorate'. It would not allow me to enter the 'find address' screens' (it would time out and act like I hadn't pressed a button.) And then it started showing me the 'insert a navigational dvd' message when I started the car. After a few minutes (up to 15 minutes), the system would recognize the disk and then start working again.

Now, the system will 'occassionally' recognize the disk and load the maps, but 95% of the time will not leave that error message screen.

This doesn't interfere with the radio, but it is quite annoying. Does anyone know any ideas on either how to 'reset' the system or to diagnose what the real issue is?

Thanks in advance,
William

Who was the disc purchased through? New or used? And what is the part number on it. It may be the case that there was a problem with the unit prior to purchase, which could explain no map disc. Here is one of many bulletins that may apply. The possibilities on nav radio concerns are many, and the radios are spendy. First is to verify that the disc is correct for the vehicle, and that it is in good shape. Here is that bulletin.
#05-08-44-012: Navigation Radio Inoperative or Does Not Recognize that a Map DVD is Inserted (Replace Navigation Radio) - (Apr 20, 2005)

Subject: Navigation Radio Inoperative or Does Not Recognize That a Map DVD is Inserted (Replace Navigation Radio)

Models: 2004-2005 Cadillac DeVille, XLR

2005 Cadillac SRX

with Navigation Radio (RPO U3R (DeVille), U2V (SRX), U2R (XLR))

Condition
Some customers may comment on an inoperative navigation radio or that the navigation radio does not recognize a map DVD when it is inserted into the radio.

Cause
This condition may be caused by a problem with the thread motor inside the radio. The thread motor moves the arm that holds the laser in order to read the information from the map DVD.

Correction
Verify that the only customer concern is that the navigation radio does not recognize that the map DVD has been inserted into the radio. If the customer concern is anything other than this, refer to the Diagnostic Starting Point-Entertainment procedure in SI to begin your diagnosis.

If the only customer concern is that the map DVD is not recognized, then technicians are to use the following procedure to resolve this customer concern:

Eject the navigation map DVD that is currently in the radio.
Visually inspect the DVD for scratches or other damage.
Reinsert the map DVD and press "I Agree".
If no map information is displayed, eject the navigation map DVDs and insert a known good map DVD. If the radio now displays map information, the customer's original map DVD is defective.
Important: Remember to remove any DVDs that are in the radio before it is sent out for repair.

If map information is still not displayed, replace the navigation radio. Refer to the Radio Replacement procedure in SI for more information (Document IDs 792964 (DeVille), 702067 (SRX), 1212196 (XLR)).
