The greatest motorcycle intercom system as-of-today.
Uses Bluetooth 3.0, and allows 6 people to conference (!) with up to 2.4KM (!!) between the first and last (using what seems to be an advanced peer-to-peer relaying of the information - nice!).

All my buddies are getting it together, so we are one happy family! :)
A bit expensive but got excellent reviews.
Revzilla has a great deal going on (not working for them..just like them).
I got the twin pack, and split the cost with my friend.

Interphone F5- webBikeWorld

Once I get it, will post my actual impressions.

Would be interested to hear your thoughts - I sent an e-mail to the manufacturer, and they indicated that I would only be able to pair 3 devices (including GPS, Cell, iPod and other Interphone devices), so I will be interested to hear if it can handle 6 riders AND the GPS & iPod (can definitely live without the cell).

Am also interested if you can plug in a GPS into the 3.5mm jack and have an iPod paired via BT (one of my Riding buddies has a GPS that does NOT have BT) - have not found one of these units that can do this yet.

TIA,

GG

Sure I will do so, but initially I would have only another F5 to pair with.
As for devices - I want to see how it pairs with my BT GPS (Garmin Nuvi 765T) and also my Android Phone. The Nuvi acts also as my Media Player.
My concern is how the music player works in conjunction with the intercom. Is intercom going to be a mode (constant) or a quasi-mode (just temporarily when Press-To-Talk).
If the former, it might be not so comfortable to use due to the constant switching - I'll just have to wait and test. Surely the manufacturer has figured something out.
Not sure why you think 3 devices can be paired - the Revzilla site clearly states up to 6 riders.



In terms of bandwidth, BT 3.0 allows that many connections at high fidelity Stereo.

And that is why I ask :)

Through the above website, I sent a few questions regarding the unit and that is when they came back with the 3 device comment, which is what confused me (as I had the same understanding - up to 6 riders). The 3 devices may be independent of the rider connections though. That is what I am trying to figure out.

Anyway - the device looks like it has promise and am interested to hear your thoughts.

I think I know what confused you - the 3 devices probably refer to the F5's ability to connect to three different BT devices such as a smart phone, GPS and media player.
The 3 devices seem to be independent of the rider count.
In fact, the user manual states that any number of riders (intercoms) can connect, but 4 is the optimal, and the sound quality degrades with more connected intercoms. Looking at the rider diagram (400m between each rider) it is highly likely that intercoms acts as relays to each other, passing the messages along.

I think the F5 is a device with 4 internal BT modules - three for non-intercom BT devices and one for BT intercom, and the BT intercom devices competes for a time slot on the bandwidth.
That can explain the comment on infinite number of intercoms and also the degrading audio quality; a behavior expected when several communication devices compete on a limited bandwidth (reminds me of the Networking course I studied in University when learning Computer Science; I wonder what algorithm is used inside..)

That makes more sense!

After going back and forth with the folks from Interphone, your interpretation appears to be correct - at least from a # of pairings perspective (can't comment on the # of BT modules). So it's back on the consideration list.

Great.

My F5 has been shipped yesterday. Once I get it next week I'll post my initial review and impressions.

Just a quick note that the WebBikeWorld page referenced in the OP has now been updated with their full review:

Interphone F5- webBikeWorld

Looks good! I really like my Interphone F4 and will keep using it this season. I plan to get a nicer helmet during the year-end closeouts, and might get a single F5 at that time to go with it. Then I can keep the F4, which works with the F5, on my current helmet for a backup or pillion.

BigMan, did you get yours yet?

The F5 is paired with the android, but can't get it to pair with the Nuvi 765T
F5 insists on password 0000, Nuvi on 1234.
No device will provide a way to customize that password..
The Nuvi shows a dialog underneath an "attempting to connect BT phone.." message.
No option to cancel - just stuck :furious:
This should go the 'Hall Of Shame' for user interfaces, alongside Lotus Notes.
Who are the idiots in Garmin that designed these things?? :headbang:

Maybe there is some hack to force the Nuvi765 to use 0000?

EDIT:
I figured it out.
The Bluetooth Audio menu actually works because it uses a hard coded pass key of 0000...
It works but I don't like these hard coding.

Edit 2:
Media Streaming with Nuvi works very poorly, probably due to the way Nuvi 765T has its BT stack.
The media plays fine, until I hit the Intercom button on the F5, then when I get back to 'Streaming Media' the GPS goes nuts and the music gets stuck. Nothing helps but rebooting the GPS
Obviously a very bad solution.
I tried the Auxiliary mode (wired plug-in) and it works fine with the GPS (of course), but then I loose the wireless and media control features - wires tangled around my body again, and I need to operate the Nuvi's screen. F5 was supposed to solve that. But it is the GPS's fault.

Maybe I should replace the Nuvi with a modern large smart phone that has a proper BT stack? (my family minivan can use it, the GPS there is too old anyway)

The phone feature works great, and even allows voice dialing.

UPDATE:
After more testing with iPhone 4S and other GPS, I have come to a conclusion that the F5 doesn't work properly with BT.
Intercom seems to work fine (in the house), but I bought this very expensive device for BT connectivity.

Returning it to Revzilla tomorrow.

That's very disappointing to hear. Garmin's BT stacks have been known to be a bit flaky, but the software in my F4 seemed okay. After some wrangling, I managed to get it working properly with my Zumo 660:

iPhone 4 -[BT headset]-> Zumo 660 -[BT headset + A2DP] -> F4

The Zumo MP3 player is fine, and it connects with my iPhone for contact transfer and headset (not that I would ever take a call while riding). It appropriately interrupts music for the GPS and phone interrupts, and my F4 AVRCP controls seem to work okay. Never tried the intercom as I don't know anyone else with an Interphone.

I think I might stick with what's working for awhile.
