General Specifications
Roadster 2
About the Product
The Motorolla T505 certainly adds a twist to the normally standard line of handsfree speakerphones. The built-in FM transmitter and StationFinder feature makes it an outstanding choice, even if outgoing audio could be slightly improved.
Roadster 2 automatically turns on and connects with your phone when you enter your car. When you're ready to leave it automatically turns off, saving battery life. Listen to calls or stream music on a powerful 2-watt speaker or through car speakers using the FM transmitter. Have crystal clear calls with Crystal Talk technology on Roadster 2. Your speakerphone's dual microphone noise cancellation and echo control settings block out background noise in the car better than other speakerphones.

What customers say about "Key Specs"
Motorola T505 Bluetooth Portable In-Car Speakerphone
  • Recognized as a Bluetooth headphones an can receive and transmit music.
  • Play music on your phone, through your car stereo!! HELLO!!
  • Having speakers on the device itself is almost pointless for those who appreciate good sound. However having the ability to connect to your vehicle FM radio changes everything. LOVE THIS OPTION!
  • The voice is very clear on both ends as no one complaint so far and no one repeated the what i am saying.Also end of week i asked them do they see any difference. they didn't know that i am on hands free in a car.
  • Audio quality not quite as good as CD.
  • Not always the best choice on finding an available radio station, but rarely more than 2 attempts required.
Motorola Roadster 2 (89556N) Speedy Conversations
  • The battery lasted me all week on a single charge while using it about 1-2 hours every day.
  • I tried to use the built-in speaker since FM was not working well. The built-in speaker tends to work a bit better, but the sound quality itself sounds like a tin can. It almost sounds like its echoing.
  • I really like this hands-free unit. It pairs great with my Windows phone (no giggles please). The windows software will read incoming text messages and generally handles the bluetooth connection well.
  • Once you've synced your phone for the first time, the unit syncs automatically when turned on or when your phone comes in range (most of the time).
  • Over all, I am very pleased. I spend a lot of time in my vehicle making calls and listening to Sirius. This product is much better than the previous BT devices I've used; to include the Himbot HBO1 and LG 750 ear buds.

What customers say about "Size & Weight"
Motorola T505 Bluetooth Portable In-Car Speakerphone
  • Compact Size/Light Weight - It's never in the way!
  • Small unit easy to mount and remove for charging.
  • Compact and very handle and simple to use though.
  • Excellent compact design with well placed controls.
Motorola Roadster 2 (89556N) Speedy Conversations
  • The Roadster 2 is very compact and lightweight, but packs a much higher punch in loudness and clarity I did not expect from its size.
  • The size was way smaller than I was expecting for some reason. It is really about the size of a large garage door opener.
  • It is small (about the size of a deck of cards) which is good because my visor mirror isn't in the way of the clip.
  • At first let me say that that thisis product is nowhere as it is pictured. It is about the size of a folded wallet...thank goodness.
  • It's about the size of a cell phone. It fits nicely and securely onto the visor.

What customers say about "Features"
Motorola T505 Bluetooth Portable In-Car Speakerphone
  • Strong transmission power (works in my wifes Matrix with a rear antenna - not all FM transmitters do).
  • Before buying i had doubt about duplex technology.Even though this unit lacks duplex technology,you wont see any difference in real world.
  • Music streaming is flawless.The inbuilt FM transmitter is very strong.I have my antenna in front side,so i never had any hiss or static.The music or calls are of CD quality.
  • The transfer between unit and radio is very easy.Just hold the FM button until the white led turns off to bring the voice back to unit.
  • Placement of the FM channel change button is on the back and a bit of a pain to manipulate while driving.
  • Can connect (pair) to only one device at a time (there may be a way around this but I haven't searched real hard.
  • Does not read NAMES from phonebook, only numbers when calls are incoming.
Motorola Roadster 2 (89556N) Speedy Conversations
  • The recorded voice tells you the station the device is using (which is typical), but if you hold a volume button down, the unit will automatically scan the FM spectrum until it finds an unused frequency, then announce the channel.
  • Launching Phone Commands! This was by far the most annoying part of the Jabra that worked very poorly.
  • The FM tuning feature on both seem to work about the same, which is to say, not greatest. I'm in the Chicago area and it's hard to find blank frequencies that work consistently.
  • The FM transmitter feature, LOVE! I can use the car speakers to hear my calls OR I normally use it to play music from apps on my phone.
  • There are a lot of great features that have been commented on by others, like auto locating free radio bands, if you use the FM transmitter.
