Help! I currently have an IPAQ 3800 with TomTom2 (upgraded) and the supplied antenna and leads. I wish to upgrade to a CF antenna with CF jacket so as to enable use while walking. In addition it would be useful to be able to use the CF antenna in my laptop PC via an adapter. My questions are as follows: -
1 Is it possible to purchase an in car power lead that replaces the current TomTom one, as the jacket removes the need for leads?
2 When walking, does the power draw from the IPAQ battery, or am I correct in thinking that some CF sleeves also hold additional batteries?
3 The CF antenna will work with an adapter in my laptop. Will TomTom 2 software also work, or will I require a different type of software?
Thanks |

Hi there
1) yes, you can purchase a standard iPAQ cigarette lighter charger
2) The power draws from the iPAQ battery and from the jacket battery (if you use a PC Card jacket or a CF Card jacket with battery). That's one of the reasons why we do recommend BlueTooth nowadays...
3) You will need to use other software. TomTom doesn't have a desktop component. Try Deluo Routis for example _________________ Lutz

Thanks.
Being a novice I presume Bluetooth is cordless? I know that my current IPAQ is not Bluetooth enabled. Therefore is this possible and if so how would it connect?
Thanks for the software info, I'll look into this. |

Yes, BlueTooth is cordless or wireless as the like to call it . For your 3800 there is not much you can do apart from using a Bluetooth CF card - but that will again drain your battery.. So you will have to stick to your CF GPS card. But try to use a PCCard jacket rather than a (battery-less) CF Card jacket. _________________ Lutz

Sorry I didn't notice you are in the UK. How about TravRoute CoPilot then? They have both a PC and PDA version. _________________ Lutz

Has anyone tried using an Ipaq 4150 and a bluetooth GPS such as the Pharos unit with the Ostia softwae?
Thanks

The rules on expansion packs and batteries changed from the 3800/3900 series to the 5400/5500 series.
However, the one thing you probably don't want (on any iPAQ) when trying for the optimal extension of battery life when using a CompactFlash GPS is a PC Card expansion pack - which, in any case, is an expensive option.
On any iPAQ, the PC Card Expansion Pack Plus will not power the iPAQ with a card inserted; the external battery powers only the card and, I believe, the expansion pack. This limitation is to do with the possible need to provide 5V power to the card - something that a CompactFlash expansion pack doesn't have to do. I believe the old (and now discontinued in favour of the "Plus" model) PCMCIA expansion pack, and the dual PC Card expansion pack all behave in the same way.
The best expansion pack if you want a CompactFlash slot and additional battery life is the CompactFlash Expansion Pack Plus. On a 3900 series, and I believe a 3800 series, this expansion pack always shares its battery with the iPAQ (whether or not there's a card inserted). On the occasions when you don't need the extra battery, you can remove it and fit the supplied blanking plate to save on weight (the PC Card Expansion Pack Plus only works with a battery fitted; it's larger and heavier than its CompactFlash cousin).
I believe all expansion packs behave somewhat differently on the 5400 and 5500 series (if I remember rightly, it's less likely that you share the battery power on the newer machines and I have a feeling that the difference is that the iPAQ will never draw power from the expansion pack battery when it is turned on) - but that's immaterial here.
It also has to be remembered that the current draw of a SiRFstar IIe/LP based CompactFlash GPS is not tremendous - and that there is a power penalty for turning on the Bluetooth hardware in a Pocket PC. The GPS will draw more than Bluetooth, but it's closer than you think - probably no more than a 60mA difference (even less if you set the GPS onto trickle mode). That extra current draw shouldn't shorten the runtime of your Pocket PC by more than about 15-20% - and that's being somewhat pessimistic on the efficiency of the power circuitry of the iPAQ.
On my setup, because I'm using a PC Card Expansion Pack Plus (I went PC Card for reasons unrelated to GPS - this means that my CompactFlash Haicom HI-303MMF is used in a CompactFlash / PC Card adapter), the expansion battery powers the GPS and the main battery the iPAQ (in my case a 3970 running Pocket PC 2003). The main battery is likely to go flat long before the expansion battery!

Sorry for the delay......been away from the PC for a while.
That helps a lot. To summarise I beleive you are saying that it is better to run the CF antenna through an adapter into a PCMCIA adapter (and then jacket), rather than into a straight CF jacket. The reason for this is the sharing of the two batteries, rather than each device running off it's own dedicated battery?
You indicate that you are running a similar set up. Have you any idea how long the whole system would run from both batteries, presuming GPS is set to trickle? No fun in setting out on a long walk, without being able to get back!!!! I presume spare batteries can be bought for the jacket as well, extending the life still further? |

I'd say that the best option is the CompactFlash Expansion Pack Plus - as that is more flexible with power than the PC Card Expansion Pack Plus. The CompactFlash Expansion Pack Plus is cheaper, slimmer and lighter than the PC Card Expansion Pack Plus - but won't work with PC Cards.
On the 3800 and 3900 series, as I described in my previous posting, the CompactFlash Plus pack has two advantages. It can share batteries with the iPAQ even with a card inserted, also it can be used without a battery.
My setup, which uses a PC Card Expansion Pack Plus, uses the expansion pack battery for the GPS, and the iPAQ's battery for the iPAQ. The iPAQ is likely to go flat first - so think what the battery life for your iPAQ is without an expansion pack.
You can get additional batteries for the Expansion Pack Plus series, including a high capacity option - though things can get very heavy and bulky. I had a battery clip fail on an Expansion Pack Plus - for no good reason, as I wasn't exchanging batteries. The battery kept falling off in use.
I sent the expansion pack to HP under warranty - after about four weeks pondering their options, I got a brand new expansion pack and battery in exchange! I would be wary of changing batteries too often - the battery clip (which is part of the battery, rather than the expansion pack) looks a little fragile to me.
