I put my receiver in the middle of the lower edge of the rear window (so sort of below the spoiler), because I had best reception there. Before, I had the mouse 'inside' my dash, hidden below the passenger side vent. However, that obscured satellites that were lower on the horizon, coming from the side where the side of the car is, and also the roof hides some sats.
I also had the receiver on the dash, in the corner where dash and windscreen meet. Putting the receiver more towards you dimished reception considerably, probably because the windscreen is tinted/heat reflecting. So that's why I wonder if the 'all-in-one' solution works well: it is on the edge of your dash, far from the windscreen and with part of the sky being obscured by the roof.
However, if you're not a DIY person, you will probably not like to unscrew/unclip major parts of your dash and/or panelling to lead your receiver elsewhere. It's a compromise in any case.
Therefor the fully 'cordless' option that tdi mentions will suit your need for simple installation and moveability.
Your 3.5 year old Ipac might just work. Like I said, mine is (over) 4 years old. It 'only' has 32Mb ram and a 133 Mhz MIPS processor but it works fine. If your Ipac is similar, then you might get away with buying just the software, some leads (or GPS sleeve) and a PDA holder.
Also, whatever you buy, new or old, the software will install on your PDA, but the maps are ALWAYS too big to be installed on it too. So you need to buy a suitable memory card for the PDA you use.
Sounds complicated, but it really isn't. If you knew how to connect your old PDA to your pc, then you can also install TomTom now.
Oh, about the mount. The vent mount is nice, but it blocks a vent and I personally find it a bit too close to me and too far from my passenger (which should/could also look along). Nor can the vent mount be 'bent' to dimish reflections when the sun shines in at odd angles.
So I went for the flexible gooseneck mount with suction cup. I'll post some (bad, mobile phone) pictures tomorrow.
And more final words: wrong directions. In TomTom2 I ran into some strange stuff, but that was very very coinidental. Also, I don't know how good the maps for the UK are. The Dutch maps are great, as well as the others I've mentioned.
Moreover: with a satnav you never get lost, even if you take a wrong turn. It will always re-route you. I love that when I'm on a holiday! No more arguments over paper maps! (but take one along as a backup anyway, in case you lose reception
)
Cheers,
Edo
