This is embarrassing. I had my 1435TM for a long time. The battery failed me once and I replaced it. The TomTom worked again for quite some time. Then the battery (I thought) failed me again. I replaced it, but alas, it didn't come back to life. I tossed the unit with the intent of buying a new unit. Looking at the forum, I see sometimes TomTom offers incentives to previous customers. While I have an account with TomTom, I no longer have the unit. I regret I may have missed out on a discount. Since I didn't know how to directly contact TomTom, I thought I'd post this on the forum if anyone knows of any discounts.
