Nice Unit
I just finished installing at KT-SR1000 kit in my 2003 Infiniti G35 sedan. The built-in Bose radio does not have a line-in port so I am presently using the built-in FM modulator (on 88.3MHz in local area). The unit is somewhat large, and ended-up being mounted on a shim-plate on the upper-center console; no problems. The display is quite large and legible from the 2-3 foot viewing range, and the combination of red lit matrix display and auto-dimming works quite well at night. The built-in FM modulator is very effective in terms of overpowering any residual in-band noise in the (choice of 4) FM bands; the signal-to-noise ratio is very good, no pops, hum, buzz, etc. As for the sound quality of the wireless FM modulator, I am a comm engineer and have placed the unit on my test equipment to measure the bandwidth and dynamic range response; the results are quite good vis-a-vis similar products, but does leave significant for improvement in the high frequency response >14 KHz. I was tempted to opt for a wired FM connection with a switching box, but decided against that as the digital to analog (2v-PP) and analog preamp is common to both wireless and wired and only final gain/amplifier stage is skipped. I doubt that the final stage is the limiting factor in the upper band tailoff so I just stayed with the wireless FM setup. Drops and fades are minimal (just line-of-sight obstructions and the combination of heavy tree foliage and periodic low satellite elevation angles. So..the bottom line is: inexpensive, easy to use, easy to view, a tad big, gets warm (but not excessive), sounds very good on built-in FM modulator, has room for further sonic improvement (wired connection to receivers with line-in).
