 |
|
 A year on and Navman have not only released a cut down version of the iCN630 (dubbed the iCN620-with UK only maps and no 3D view) but they have also upgraded the iCN630 to Version 2 aka iCN630 V2.
We produced a mini review in February which was tailored more to existing Navman iCN630 owners, and people who have already tried the original iCN630, but this is now the full review that many of you have been waiting for! How do we rate the iCN630 V2 ? Read on!

Hi David
A very good review, however in the Technical Specification you show the Processor as an Intel PAX250. This was the processor used in the original iCN 630's. I think you will now find that the iCN630 V2 and iCN 620 now incorporate the Intel PAX255. In saying this though, it's a bit confusing when the Product Brochures on the Navman Website shows conflicting information and quotes both versions.
Regards

Hopefully you have the answer to this. In your review you talk about the size of Memory Card being used in an iCN 630, and you go on to say because of the size of the maps you might like to purchase a 256Mb or a 512Mb.
Whilst their Technical Spec. says up to 512Mb, Pages 9 & 71 of the iCN 630 V2 Navman User Guide limits the maximum size of card you can use to 256Mb.  In fact it says for general use a 64Mb or 128Mb is recommended.
During your comprehensive review, did you try a 512Mb Card and if so did it work OK  It would be nice to know cos as you say they have really come down in price recently.

You mention the routing algorithum having something wrong. I can tell you the basic problem (I think!). The average speed used is incorrect.
I was today in the centre of birmingham (After being directed down the Aston distress way - actually a good move cos of the traffic!) but it said I could get to my house in about 7 minutes - and was 6.7miles away. There are no roads that you can do 60mph down, let alone average 60.
Whether it is a problem with the geodata or the algorithum I don't know!

Intel quietly stopped making the PXA250 some while back and moved all production to the PXA255, which can be used as a drop-in replacement for the PXA250.
I'm a bit rusty on the precise hardware differences between the two - there are some errata fixed on the 255 (I believe the most significant fix is a bug in one that is present in the PXA250's use of its caches), also I believe the 255 can support a 200MHz memory bus if the memory bus is designed to run at this speed (this is not an automatic upgrade - the rest of the hardware has to be designed for a 200MHz memory bus). The PXA250 is limited to a 100MHz memory bus.
From memory, a PXA250 that reports itself to be a C<something> version is actually a 255. B<something> PXA250 processors really are PXA250s. You can see this information on some Pocket PCs in their Asset Viewer or similar.
As this is all from memory, I apologise if any of this is inaccurate. To an extent this is somewhat historic now, as it's something like a year since Intel made any PXA250 processors.
It's not usually worth getting too hung up on the differences between the PXA250 and PXA255.

| I have been using the V2 software for a few weeks now and so far have have no problems or complaints. I have maps loaded on a 512mb card and it does not seem to be an issue. It does take a little time for the ICN630 to load them, but then it seems to work fine. |

Alfie, I didn't test a 512mb card, Navman internally had told me back on V1 and V2 that there was no upward limit, however map sizes can be a problem like with the PPC version, but at the time of writing the manual 256mb cards were really only available under V1.
I have a couple of 512mb SD's here, but unfortunately they're fully loaded with other software so I can't give them a test. |

Dave,
Thanks for your reply, I just wondered if you had tried it with that size card. My reason for asking was there was a recent posting where the guy had bought an iCN 630 + 512Mb card and he was having problems, which appeared to be to do with with the card, and was looking for advice.
I have now sent an e-mail to Navman asking asking them to clarify the position regarding memory card sizes against their latest specification. Presumably now the unit has evolved a little more they should be in a better position to give an answer.
I'll keep you posted on any answer they let me have.
Regards
alfieB

Hi Dave
Navman replied to my e-mail today and they say that at the moment it will support most 512Mb cards. But  they say there are some slow / cheap SD cards around which are not suitable.
Again I have to admit I've not much of a clue as to if a card is good or bad, so I think I'll sit and wait until the dust settles and see what problems come up. I'm sure there are those far more experienced than me who will be able to give more advice.
Regards
alfieB

| There are always lots of problems with SD cards when it comes to PDA's in general, lots of bad ones out there, generally ones that say Made In Japan are normally the better ones. DavidW has started several discussions regarding good and bad SD cards in the forums here. |

I use a Panasonic 512MB SD. When formated in FAT16, there is no pb.
I tried with a Sandisk 256MB SD. All right to.
But there is a bug (in french version) : we can not disable some map. So the start is a little bit slow (when there are 500MB of Map). |

Hi
You have not included your location in your Profile, so I'm presuming from your comment, regarding the bug in the French Maps, that you are in France Also is your iCN at V2 + SP1
It does seem though, that the larger the SD card, coupled with the amount of maps loaded onto it ( in your case 500Mb) generally will cause the unit to run slower.
If you haven't already done so, it may well be worth notifying Navman of this particular 'bug'. Obviously the more feedback they get from Users then the more chance they have of sorting some of the problems out in future Upgrades/Service Packs.

Yes from France.

The start is a little bit slow, but the menus are fast (enough).

I already contact Navman for somes troubles. Routing algorithum is sometime really bad! And we can not disable any maps!
I will try with a smaller SD (like 128Mo) to verify the speed of the unit. |

Hi
When Service Pack 2 is released  (well that is what Navman are saying ) then hopefull they will have addressed the problems that the users have been finding.
In the meanwhile it will be interesting to see when you use a 128Mb SD Card if you can then disable your maps and if it makes any difference to the speed of your iCN.
