The Chicago Store has a trade-in program which allows you to trade in select automotive and fitness devices for a credit towards a new purchase at the store only. (Credit options vary based on model.)
If you are experiencing problems with your device, please refer to the Garmin Repair Center for online troubleshooting and information on how to send your device in for service. Garmin also offers free technical support should you have questions on the use of your product.
