If you own a TomTom GO 910 or GO 510, you'll want to read this. We had a nice chat with TomTom reps this morning, and they let us know that they're offering replacement vehicle mounts for the two models after determining that a number of units were shipped with substandard docks. There have been numerous complaints about loose power connections and the dock being unable to support the full weight of the device, causing the GO 910/510 to droop down to the dashboard (we actually experienced the latter during our testing). However, the company is hoping to right this wrong with this replacement program. Just go over to www.tomtom.com/newmount--have your product serial number handy--and fill out the required fields. The best part? It's all free.
