OEM OnStar Communication Control Module for 2010-2011 Buick, Cadillac, Chevrolet, & Saab

$ 69 .95

Product Notes

This is a used OnStar communication module. It is for vehicles with option code UE1. It also fits vehicles with voice recognition (option code UPF).

It will not function correctly in vehicles without these specific options. For the 2010 Saab 9-5, this part only fits models with the 4th VIN digit of 'G'. For the 2011 Buick Regal, fitment is confirmed for vehicles requiring part number 20842731. Installation may require programming by a qualified technician or dealership to ensure full functionality.

Returns (30 Days)

We accept returns within 30 days of delivery for this part.

  • Defective parts: We will replace the part or issue a refund at our discretion
  • Electronic parts: Must be returned with the sealed inspection bag unopened. The clear bag allows full visual inspection before opening. Once opened, electronic parts can only be exchanged for a replacement if defective — no refunds
  • Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
  • Return shipping: We cover return shipping as part of our 100% money-back guarantee
  • Parts must be returned in original packaging and unmodified condition
  • Poorly packaged returns that arrive damaged will not be credited

All used parts include a 6-month warranty from the date of purchase.

  • If your part fails within 6 months, we will send a replacement
  • Refunds are only issued if we cannot provide a suitable replacement
  • Warranty covers defects — not installation errors, misuse, or damage after installation

Note: Warranty is for replacement, not refund. A part failing on day 80? We'll replace it. But the return window for refunds is 30 days.

Damaged in Shipping?

If your part arrives damaged:

  • Stop immediately — do not install the part
  • Keep all original packaging and boxes
  • Take clear photos of the damage and packaging
  • Contact us within 48 hours of delivery
