Hello GS team,
I did put every thing together in one list.

First of all the things I like it to do (Albert):
Speed and distance true sensor, multi users on GPS
HR monitor, with belt (coded is better but could also be 5khz)
cadence with sensor
smart trackback system like GH625,561 and GH505
alarms like in the GH625, but not with first priority so easy to skip
HR alarm as little hart symbol and reverse blinking when not in set range
All totals saved in bicycle computer
avg in km/h, with actual speed an little arrow for above avg or under
pc link for downloading, evaluation and track/route uploading
external easy loading the battery
easy switch from gps map to actual bicycle screens and functions
a extended configuration to choose what to be on or off, because also the capability of multi user
Jeroen van de berg - high-resolution screen with several gray values
- high-sensitivity GPS chip/antenna
- small, light, but with screen big enough to display up to 8 customizable fields
- "profiles" to easily switch between modes (mountain bike vs. roadbike)
- powerful processor for fluent trackback
- north up/heading up switch-able
- battery life of Min. 8 hours
- waterproof
- quick-release mount
- buttons to be useable wearing gloves
- mount compatible with several diameters
- possible 2 mounts included (mountainbike/roadbike)
- F(*&%#$#-proof pc connection (Mini or Micro-USB preferred)
- virtual partner preferably
- "smart" point recording
Also, -GS, are you hearing this?- direct compatibility with GPX format is a must.
Albert Slope in %
Geographical cards in future so you can create off line( in holidays) still routes and follow them with the bicycle computer (if possible also in de bicycle computer)
Easy to use and create routes and see performance with pc software
Selling ad ones (ANT technology by GS) like power and cadence/speed and so on.
The functions whats available in GH625, 505
I like the user pages a lot in the 625, but it is now not easy accessible when in map mode.
A holder like a rubber block for the steering from the bike or other reliable solution.
- A possibility to store all totals and others, except GPS, when main battery is low
Cost price around the 200, in the shops is a fair price with inside the geographical map capability, this without the geographical maps from different countries of course.
Regards,
Albert
