A jury found Jose Luis Perez-Guerrero (“Perez”) guilty of conspiring to distribute more than 500 grams of methamphetamine, in violation of 21 U.S.C. §§ 846 and 841(b)(1)(A), and using a communication facility to facilitate the distribution of methamphetamine, in violation of 21 U.S.C. § 843(b). The district court sentenced Perez to 300 months of imprisonment and 10 years of supervised release. Perez appeals the district court’s order denying his motion to suppress evidence, and he appeals his sentence. For the reasons stated below, we affirm the judgment of the district court.
I.
This conspiracy to distribute methamphetamine in the central Iowa area is bookended by two events occurring approximately four years apart. The first occurred on or about July 1, 1996, when Deputy Sheriff Doug Lande pulled Perez over after Lande observed Perez’s vehicle’s muffler dragging on the ground. After checking Perez’s identification, which falsely identified him as Gilberto Barrien-tos, Deputy Lande observed open containers of beer in the vehicle and a round of .45-caliber ammunition on the floorboard. His suspicion aroused, Lande called for backup and had Perez and three passengers exit the vehicle. After another deputy arrived, they searched the car, finding a *781 .45 semiautomatic pistol under the rear seat. Perez was arrested for transporting a loaded firearm and for having a defective muffler.
During booking procedures, the deputies found on Perez’s person a key attached to a green key fob that read “108.” Perez stated that the key was from a hotel in Sioux City, but the deputies had found a matchbook for the Hawkeye Motel in Des Moines during the search of the vehicle and decided to investigate. They arrived at the Hawkeye Motel some time after noon and inquired about room 108. The motel manager showed them a receipt for the room made out to Gilberto Barrientos. The manager told the deputies that checkout was at 11:00 a.m. and that Barrientos had not extended his stay. The manager then consented to the deputies’ request to inspect the room. After the county attorney told the deputies that they legally could enter the room with the consent of the manager, they entered and found under the bed a bag containing methamphetamine. The deputies then obtained a warrant and seized the contraband. Perez admitted that he knew there were drugs in the room, but he denied that they belonged to him. Perez was convicted of and served time only for the weapons offense.
The final event in the timeline involves the controlled delivery of 774 grams of methamphetamine to Kelly Carmichael in Des Moines during the summer of 2000. David Reyes was present at Carmichael’s residence during the delivery and signed for the package. Moments thereafter, the authorities raided the house and arrested Reyes. Carmichael was arrested later, and she agreed to cooperate with the government.
In the years between the two events described above, the conspiracy distributed a substantial amount of methamphetamine-approximately 30 pounds-in central Iowa. Perez fronted Carmichael, among others, pound quantities of methamphetamine. Carmichael stored the drugs at the residence of Mary Muir and distributed them -in Des Moines. Randy Guerrero distributed drugs in the area and also collected the proceeds from area sales on Perez’s behalf. Although the exact dates are unclear, at some point during this time, Perez was incarcerated again for another offense unrelated to this conspiracy. While incarcerated, he continued to direct the aforementioned people to distribute methamphetamine in central Iowa, and he continued to collect the proceeds from those sales. For example, the police search of Carmichael’s residence conducted after the controlled delivery unearthed a letter from Perez sent while he was incarcerated regarding the collection of certain drug proceeds. In addition, Western Union records showed numerous wire transfers from Perez to his coconspirators and vice versa.
II.
Perez moved to suppress the methamphetamine seized during the motel search. The district court denied the motion on the ground that Perez lacked standing to challenge the search. On appeal, Perez argues that the district court erred in denying his motion to suppress. We review the district court’s findings of fact for clear error and its ultimate conclusion as to whether a Fourth Amendment violation occurred de novo.
See United States v. Mangine,
We conclude that the district court

did not err in holding that Perez
*782
lacked standing to challenge the search of the motel room and the subsequent seizure of the methamphetamine contained therein.
See United States v. Larson,
In
Reyes,
we relied on
United States v. Croft,
Perez argues that the district court

erred in calculating his base offense level because it erroneously attributed to him the 774 grams of methamphetamine sent to Carmichael in the fall of 2000 while Perez was incarcerated. Perez argues that his conspiratorial liability ended when he was imprisoned. While it is generally true that “incarceration may constitute evidence of withdrawal from a conspiracy, it is hardly conclusive.”
United States v. Cohen, 516 F.2d
1358, 1364 (8th Cir.1975). Here the trial testimony and other evidence, including the letter from Perez to Carmichael, showed that Perez had not withdrawn from the conspiracy; rather, he continued to direct others in the shipment and sale of methamphetamine and in the collection of the proceeds therefrom. Because Perez remained part of the conspiracy while incarcerated, he is responsible for all reasonably foreseeable conspiratorial acts. Accordingly, we cannot say that the district court erred in holding Perez responsible for the drugs seized in the 2000 shipment. See U.S. Sentencing Guidelines Manual § lB1.3(a)(l)(B) (2001) (stating that defendant is accountable “in the case of a jointly undertaken criminal activity [for] ... all reasonably foreseeable acts
*783
and omissions of others in furtherance of the jointly undertaken criminal activity”);
United States v. Zimmer,
Perez argues that the district court erred in applying a two-level sentencing enhancement pursuant to U.S.S.G. § 2D1.1(b)(1) for possessing a dangerous weapon in connection with the conspiracy. Specifically, Perez argues that he should not be held responsible for the loaded .45-caliber semiautomatic pistol found underneath the backseat of his vehicle during the 1996 traffic stop. We review the district court’s factual finding that Perez possessed a firearm within the meaning of § 2D1.1(b)(1) for clear error.
See United States v. Hayes,
“For this provision to apply, the government must prove by a preponderance of the evidence that a weapon was present,”
United States v. Thompson,
We have previously affirmed the application of the section 2D1.1(b)(1) enhancement where the defendant was in the same vehicle used to facilitate drug transactions.
See Braggs,
Finally, we reject Perez’s argument that the district court erred in using his prior conviction in California for aiding and abetting the importation of marijuana to calculate his criminal history category. In determining the defendant’s criminal history category, the district court is to consider “any sentence previously imposed ... for conduct not part of the instant offense.” U.S.S.G. § 4A1.2(a)(l). Conduct not part of the instant offense is conduct other than “relevant conduct” as defined in U.S.S.G. § 1B1.3.
See
U.S.S.G. § 4A1.2, comment, (n.l). “Relevant conduct” under U.S.S.G. § lB1.3(a)(l)(A) includes “all acts ... that occurred during the commission of the offense of conviction, in preparation for that offense, or in the course of attempting to avoid detection or responsibility for that offense.” Because the California conviction lacked geographical proximity to the conspiracy at issue here, involved a different drug than the one whose distribution was the object of the conspiracy, and involved different coconspirators, we conclude that the district court did not err in treating the California conviction as a separate and distinct offense and by using the conviction to determine Perez’s criminal history category. See
United States v. Davidson,

For the reasons stated above, we affirm the judgment of the district court.
