Has anyone every exchanged their old Tom Tom GPS for a new one through Tom Tom's DealTime? I have a Tom Tom XL 325 SE which was purchased in 2009 from Walmart.com. This model is not on DealTime's drop down list of models although there's an XL 325 S. My question is, if and when I decide to exchange my gps for a newer model, should I select XL 325 S or is my model (SE) not approved for exchange. Thank you.
