I purchased the Samsung Nexus 25 primarily for the XM radio capability and its inexpensive price. I paid about $30 from Sears after rebate. I liked the flexibility it gave me to be portable in the car and at home. And the MP3 player recording capability off of XM was only icing on the cake. I use it primarily as a car player now and so the use of the car kit is extremely important to me. I have to say that I'm very pleased with its quality and reception.(Even though I list the pros and cons, many of these concerns are about the NEXUS product itself and don't reflect the car kit adapter)PROS:1) Quality-wise it's well built and installed easily in my car. I have an 99 Acura RL and the YA-CP200's air vent connector clicked easily onto the vents in a convenient vent on my dash. The unit stays in place and I don't have any concerns about it sliding around or slipping out of the cradle as I drive.2) Sound quality is great. Even though I could use the FM transmitter built into the base, I've opted to use the cassette adapter and I get perfect sound. My sister has an XM receiver by a competitor and she uses the FM transmitter and when I ride with her, I hear a constant low hum in her broadcasts. I don't have that issue. I have an extra cord to deal with, but it concealed easily along side the dash so no discernible issues there.3) Remote control capability helps with use in the car. Even though the Nexus is located in arm's length reach on the dash, the car kit comes with it's own separate remote control that allows me to control the unit with ease. The home base unit also comes with a remote so now I have two and can keep one in each location. The only problem is that sometimes I'll take a corner and if I haven't secured the remote, it can end up in the foot well on the passenger side. That can be annoying.4) I love the fact that I can record the XM broadcasts on the fly. When I'm in my car and I go into a tunnel or an area where I can't get signal, the Nexus automatically switches over to MP3 mode and I can listen to my favorites until signal returns. To record a song is a simple push of a single button during broadcast. Works pretty effortlessly.CONS:1) I already mentioned that the remote has a tendency to fly around the car if I don't secure it... but that's more my fault than it is a design problem with the unit.2) The Nexus 25 receiver on it's own can't receive the XM signal. There's a separate XM module that plugs into the cradle behind the receiver that allows you to receive the signal. If I remove the XM module, then I can't get XM broadcasts. Considering the module is such a small thing, I don't understand why Samsung just didn't include the circuitry in the unit like in the Samsung Helix, the upgraded model. The Helix has the XM reception built into a single receiver unit so you can receive XM anywhere without having to plug the unit into a cradle with the module. I think Samsung was looking for different price points and it charges almost 4 times for the Helix as it does for the Nexus. Though I can understand why they've done this, I think they've done themselves a disservice.3) The navigation on the receiver is a bit cumbersome and not very intuitive. I can get the job done, it just takes me a few more clicks than I would like especially considering that I'm in my car and should be keeping my attention on the road. Once again a quip against the Nexus unit itself and not the car kit. Changing stations is not so simple and I haven't yet figured out how to save my favorite channels so I can go directly there... I'm sure there's a way to do it, I just need to get my butt to pick up the manual and read it.4) I have to reinstall the XM car antenna. I've heard from a local XM radio installer that the magnets in the antenna cause rusting of the exterior paint and seem to mess up your paint job. So my sister ran her antenna wire around the inside of her windshield and uses velcro to attach the antenna to the windsheild behind her rear view mirror to help conceal it. Sounds like a good fix so I'll be doing that in the near future.Overall, I think the Nexus 25 along with the car kit make a great addition to any vehicle!!!
