any way to speed up an older sat-nav

teedy23

I have been trying out an old sat-nav but it's painfully slow. cost £400 some years ago but in mint condition. Can any of you techsperts tell me if there is any way to speed it up, or is it getting binned? it's a DestinAtor ND

I don't know anything about these in particular. But if it uses a removable memory card, it might be worth buying a bigger one and copying the card that came with it onto it. I did this with an old tomtom and it really helped.

What do you want to speed up? Routing time? Finding your location time?

Also removing any additional maps, themes, POI, voices etc you've added over time can help a little with the general speed

The problem with these older units is that they often pre-date the really big steps forward in GPS chipsets (e.g. the SIRFstar III onward), so their receivers are relatively power-hungry, slow to lock and have poor sensitivity.

I borrowed one of about that sort of age, and it was frustrating because it would lose lock under trees (especially wet trees).

There's nothing to be done to resolve that problem, unless it has an external antenna connection, and that's a bit of a pain to rig up anyway.

The PDA-based ones (not sure if yours is) are also typically under-powered because they use a general-purpose OS (often Windows CE) rather than something better suited to that sort of device.

Drive slower so it get's a chance to catch up.
