All 11 shops listed in Montana install car stereos or CarPlay, with the most in Billings, Great Falls and Kalispell. Each listing shows its hours, Google reviews and a call button.
Prices depend on your car, the parts and the shop, and we don’t list prices. To get a fair price, ask 2 or 3 shops for a written quote that splits parts from labor. Give them your car’s year, make, model and trim, and ask whether the quote includes the dash kit, the wiring harness and any adapter for steering wheel controls or a factory camera.
Yes. 3 shops in Montana list car audio repair. Call first and describe the fault, such as no sound, no power or a dead screen, so the shop can tell you whether it fixes that unit or would replace it.
Many shops do, but not all, and our listings don’t show each shop’s policy. When you call, ask whether they install parts you bring, what the labor costs for your car, and whether that labor is covered if the part fails.
Before the cold sets in. Searches for remote start installation in Montana go from about 10 a month in summer to 320 in December (Google, Oct 2025 to Sep 2026), so shops get busier from November. 9 shops here list remote start or alarms.
5 of the 11 shops list Saturday hours, and none list Sunday hours. Hours come from Google, so call ahead to check.
Ask every shop the same questions, then compare their answers.
