510 Vs TTGo

I guess this is one for Dave or darren et al. Reading the review of the 510 it looks a good match for the TTgo as a dedicated Nav system.

Will the 510 be the "new" TTgo?

You will have to wait for the review later next week Wink

The 510 is good, has a lot of plus points over GO including it's size for one, but GO also has a lot of plus points like ASN (although I'm still not 100% convinced of ASN), ease of use etc.

DOH! I meant the press release of course.

ASN?

Ease of use is to be much applauded reading the various problems folk have in using some kit.

ASN is Assisted Satellite Navigation. It's like a giro (two planes sensor) that sits in GO (hence the size of it).

If you drive through a long tunnel and the tunnel bends then most GPS programs will continue going for a while, they'll also snap you to road, but what they cannot cope with is if there are exits in the tunnel. ASN is suppose to combat this by having a horizontal and vertical movement sensor (giro type) that detects movement in either direction and should feed that information back and plot you on the map. That way if there are two or three exits in a tunnel like there are say in Germany, then you SHOULD still be able to navigate without satellite navigation. However ASN can pose other issues because you can be standing still at a traffic light and have a low satellite fix, say 3 or 4, and due to this your positional (lat/long) data is inaccurate by several hundred meters, but as soon as your sat signal jumps up and becomes more accurate to where you are, ASN can see this and think you're in a tunnel and start to move you at the rate of the distance in that second. This can have the adverse effect of having your position travel across the map at several hundred miles an hour.

When you start driving again it should correct itself, but I have seen it to have a few problems. So ASN although it's a good feature I wouldn't purchase the product solely for this.

I guess that partly explains the , relative, high price of TTG compared to other PDA systems. I like the look of the 510 but still like the performance and maps of Co Pilot 5 despite recent probs found such as in multi recalculation causes lock ups. In all these things its looks like one mans dead end is another mans dual carriageway. Like all IT just make your choice. You're always gonna be wrong and something belse will come along. You pays your money........

TomTom GO really is at a cheap price. Going back a year ago a complete Pocket PC, GPS Receiver and GPS Software would cost you in the region of £650-750, it's only recently with added competition that prices have come down on a lot of PDA bundles with the introduction of cheaper cut down Pocket PC models.

The 510 will retail for around £499 but you may see it cheaper in some retailers.

It really does come down to personal choice. Most people will go for athetics, design, software look and feel over core features.

Indeed, prices always change. You just have to bite the bullet at any given time. I've posted a question of the SOC CF site which may affect my decision

SOC CF = SysOnChip CF Card. Not sure why, I think he posted to the wrong thread.

Only becuase the Sysonchip CF seemed to be a good, cost effective option but the early reviews were good but later feedback was poor. I was just wondering what the latest was before I choose. However, I have picked the 2210, CP5 and Fortuna Clip On as giving me a bit more than just Nav system plus with Co Pilot 5 I think a better solution than Nav man. Good though the 510 is reported to be.
