Who knew Garmin would be celebrating their 25th anniversary as of this year? As part of the celebrations, the navigational service is offering exclusive trade-ins (for the first time) for customers. Those wanting to take part can trade in their automotive GPS whether its old or new, functional or not, even if it’s another brand — and the guys at Garmin will give you R300 off the purchase price off a new Nuvi 55LM. This offer is valid until 31 July. Then again, the Nuvi retails for R2000 at selected retailers.
