If I recall and I do remember Android does have a app that you can put on their phones and tabs that will let you change the station from your phone or tab. I have the 21's (android) and I just left the little slide selector on the unit where it was. I have perfect reception where I live, others may not so this feature may really be handy to do it from your phone or tab. If you do have to change the station and don't have the feature on your phone you must be able to access the little box and the slide switch to change channel. I don't know if apple has a app to allow you to do this. I just never checked it out. Call the number or email in my earlier post or maybe call Apple.

I have two of the ISFM21 installed in two different cars. They work flawlessly with absolutely no problems. The way the company Isimple Transit Blu is marketing the units. The ISFM21 is for the Android market and the ISFM22 is for the Apple market. I have a Apple phone and my wife has a Android phone and we both can connect to either car with no problems what so ever (one at a time of course). Isimple does have a phone number 866-788-4237 and here is their address if you want to email them. https://www.isimplesolutions.com/contact.aspx The 21 is Android and the 22 is Apple. But I don't think it matters which phone you use when you purchase the 21 android model. At least it didn't matter in my case. How ever if you purchase the 22 I'm not sure you can use either phone. I would just call them to find out for sure. But I can attest the 21 units work perfectly. You do have to dissemble the dash of your car somewhat but I guarantee you, you will not be dissatisfied with the quality of music you get from your car stereo. It's so nice to stream wireless bluetooth Audio. This product does exactly what it is designed to do. I highly recommend it to anyone. And for what it's worth I am going to purchase a third unit for my wife's car. The other two units are in a Corvette and a Z28. You may need to purchase (or may not) some extra short cable adapters depending on what make of car you have. On a five star rating this product is a very solid five star.

agree with Terry...22 is for Apple, 21 is for Androids...but my son's apple works with it without any problems.

i agree with all of the above answers. i have the isfm22, but my ipod touch and my android both connect to it without issues.

Actually, I don't think there's any difference in connection time for an iOS device on the 21 or 22. Both the ISFM21 and 22 use the A2DP Bluetooth standard, but only the 22 will allow an iOS device to use the TranzitBlu app to switch which FM frequency is used.

In the specifications portion of the Amazon ad the model is stated as the ITP280B. I bought this item as a gift and the person I gave it to loves it.

The IF-221 is 2 inches shorter, .2 pounds heavier, and does not have the firefighter symbol. It is also $10 cheaper.

ispring tds-3 is of better value as it has temperature compensation feature. The results have always been consistent for me.

The ENH 700 EXT has a dual band frequency transmitter to provide better coverage and handles newer technology, whereas the ENH210EXT has only a single band radio. If you are using only wireless N and dont plan to connect to the 5GHZ band then go with the 210.

The difference is in the remote. The FFRE1233Q1 includes a temperature sensing remote. This model does not include the temperature sensing feature. IMHO, the temperature sensing doesn't work that well anyway, and is something of a gimmick, so buy this one and save $30. But it's your call...

I have never owned a 660, so I can't really help you as to the specifics between the two. I thought the only difference is the 660 doesn't use XM for sat radio, weather and traffic. I will say, I have had 3 665's. The first 2 failed under warranty. My current one still shuts down, maybe once on a long ride, for no particular reason. I assume you've read my review of the 665 on Amazon. The 550 was a much better unit, but didn't have the NEXRAD radar.

Check out these specs of the TM722G and TM822G. They both are DOCSIS 3.0, have the same number of upload channels (4) and upload speed (up to 122 Mbps). Main differences are TM822G has 8 download channels and up to 343 Mbps download, while the TM722G has 4 download channels and up to 160 Mbps download. Also it appears that the TM822G has two RF channels to assist in download, whereas I think the TM722G just has one. arrisi.com/product.../TM722G_07JAN10.pdf arrisi.com/products/_docs/TM822G_TS_24JUN11.pdf arrisi.com/products/product.asp?id=80

To be honest I don't see any difference. We purchased the 20632 and my husband loves it.

The primary difference is the addition of an on/off button on the front panel of the 641P. As far as I can tell they are identical otherwise.

If you buy the ISY-994i Controller from Orchestrated Home and click on their logo to see all their products you will see the 2413S PLM there. If you add it from their Amazon Store front, the two are packaged with a discount. Both have to be purchased concurrently from Orchestrated Home.

I'd say its a M3 version, but to make sure please go to this link: http://www.pivosforums.com/

I don't know what the difference would be, I wasn't aware that there were various models. Sorry I couldn't be of assistance.

As far as I know, the only difference between the two are the color of the buttons and the packaged software. Solid unit either way.

There is no difference in the two as far as I know - they are just on different frequencies so if you owned two they wouldn't interfere with each other. I own the 27 MHz and it works great - and this is a good price.

Yes, a good one. I,m using the UMC 200 and it is excellent. The difference between a fine one and a common one is like day and nigth. I was very surprised.
