no problem before.. On vacation and ready to drive home and radio/ gps system working one minute and then it completely shut down?
Radio/ gps system stopped working altogether, problem? on 2009 Buick Enclave
I can only suggest first looking at the fuses in the fuse box (hopefully they are identified on the fuse box cover or described better better in your owner's manual).
