BuyDig offers the Garmin nüvi 52LM 5" Portable GPS Navigation System with Lifetime Maps, model no. 010-01115-01, for $100. Apply coupon code "VMEDEL" and pay via Visa Checkout to drop it to $77. With free shipping, that's tied with our mention from last week and the lowest total price we could find for a new unit by $21. (It's also a buck less than the best price we could find for a refurb.) Features include a 5" 480x272 touchscreen LCD, lifetime map updates, voice navigation, lane assist, and microSD card slot.
