MEMORANDUM**

Antonio Gonzalez-Radiya appeals the sentence imposed following his guilty plea to unlawfully entering the United States *880after having been previously deported in violation of 8 U.S.C. § 1326.

Gonzalez-Radiya contends that the district court erred in applying the Sentencing Guidelines as mandatory when imposing his sentence. Because GonzalezRadiya was sentenced under the then-mandatory Sentencing Guidelines, and we cannot reliably determine from the record whether the sentence imposed would have been materially different had the district court known that the Guidelines were advisory, we remand to the district court to answer that question, and to proceed pursuant to United States v. Ameline, 409 F.3d 1073, 1084 (9th Cir. 2005) (en banc). See United States v. Moreno-Hernandez, 419 F.3d 906, 915-16 (9th Cir. 2005) (extending Ameline’s limited remand procedure to cases involving non-constitutional Booker error).
