i have a 5/6 year old sat nav.by navagator. i say it works well because i know how it works most of the time what i want to know is "if" i put a new map/chip update [which the company is selling in there new machine], dos my old machine work/use "all" the new gizmos thats "printed" on the chip or only the old road info i got,updated, [like the new machine tells you, when to get into a certain lane]. its £118.00 for a new sd chip. when i can get a new tomtom go730 t for £215.00 in a new machine thats got 1 years gtee come on roy or one of the lads, help
Hi George, I'm quite lucky I use the XDA orbit 2 phone from O2 this came with Co Pilot 7 live installed I get a new one each 9 mths when I upgrade the phone, very useful as Donna now has my last one as a sat nav in her car and I still have my previous one spare in my case just for emergencies. This has saved a fortune as the software is up to date each year and I dont pay a penny for the upgrades.
So if your on a contract phone it might be worth looking to see if you can get one with this sort of software built in.
So many changes for the new year... 4 X 4 drivers do it off road...
Hi George, I use a Medion satnav which is about 18months old now. To update the maps is going to cost £105.00 which is ridiculous when one can buy a new Tomtom for about the same money. I'll continue with the old one, thank you. It does all I want it to do. I suppose I might go for it if the programming told one which lane to get into (very useful when towing) but I can't find any details of exactly what one is getting for one's money. As regards giving advice, I am sorry George, it really is a minefield and I would hate to give you duff gen. So I'll dip out on this one. Roy
Hi George, I have a Tomtom GO 730T which I am very pleased with. However there are a few problems that I have complained to Tomtom about, which I doubt they will ever resolve. The map provided has some errors, such as a new roundabout and road near my home that are not on the map. I got a free updated map, but the errors are not corrected. The roundabout and road was build in excess of 5 years ago? Tomtom appear to be reneging on providing HD Traffic for the GO *30 range which came out earlier this year. I doubt you would have a lot of success upgrading your satnav with the latest chipset, software and mapping. Everything would need to compatible, so you could be just wasting your money. Given my past experience with Garmin and Tomtom, my money goes with Garmin. Tomtom customer service appears very poor.

thanks lads, if i keep with my old one, and if i come across a new road/motorway, i will see what the signs say, and if its the way i want to i will follow it, and im sure the old sat nav will correct me when i get to the other end. or the ginger one will. just in the passing, is there any clever thingy forum that maybe able to help, that you know of ?? [like sticking a tomtom chip in a garmin/directions/navman etc, without it blowing up, as the unit only reads the chip, dont it]
It is unlikely that all of the features will work with a five year old sat nav system as the GPS chipsets used back then were not as accurate as the latest generation devices. It will probably be only the map updates that would work from the new SD card.
The new chipsets such as SiRFstar III are a lot more accurate and communicate to a higher number of satellites hence they can now have features to tell you when to get into the correct lane. The modern units also cope a lot better with short tunnels and have a lot faster startup time.
It is highly unlikely that you would be able to just change the chip in an existing sat nav due to the difference in the architecture used. They tend to run off a lot lower internal supply voltage (I believe that some now use a 1.2V supply). Also the new chipsets use BGA packages which require the use of specialist equipment to process. The other problem is that the GPS chipset is the most expensive part of the GPS unit.
Unfortunately GPS units are designed to be obsolete in 3 years due to the way that technology is constantly changing. In a few years time you will be able to purchase sat nav devices that will operate underground as these are currently in their development phase.
