Would be suprised if there is no interference, as all fm transmitters are hamstrung by broadcasting laws governing max signal strength. But then, for a fiver....
Having said that I am pleased with my Harman Kardon, but then it has a hard wired input to the aerial on the back of the HU so minimising signal loss, direct control for older iPods and 3.5 mill jack input so newer stuff works too for audio. iPod input seems to pick up some disc noise from the 3rd gen iPod, this noise is minor and is not present using iPhone 4 via the 3.5 mill jack.
iPhone 4 with tomtom and it's built in iPod via Bose.
works well as the phone mutes the music to play tomtom commands, and because it's broadcast as a radio station all the other inputs mute the music nicely to voice over the top.
And btw, voice activated dialling (iphone 4) works brilliantly with Nokia ck7(?)w Bluetooth car kit. Press and hold menu button, while music and tomtom are running, speak the name as recorded in the phone book, and the call is made via Bose. Tomtom runs on screen during the call. Smart!
Really pleased.
(There where some challenges integrating bt car kit with 2015 phone btw, but VXL V6 and TB built and installed a custom loom to make it work, for which I am eternally gratefull
)
HK transmitter £20 off eBay, direct control and charging of older 3rd 4th and I think 5th gen iPods, with 3.5 mill jack input for everything else.
