Something I found on ebay, that I thought might be of interest to some of you.
I know its not GTR, but I'm sure it could be adapted.

For those of you with an Autocom ....
I've just got myself one of these....
http://www.tesco.com/direct/technika-dab112-portable-dab-radio/208-6909.prd?pageLevel=&skuId=208-6909
connected to the Autocom, the headphone cable is the aerial..... now in the past I've tried a few and got mixed quality DAB reception... so this time I used a splitter, and put an extra aerial cable in around the front of the fairing ( inside of course)
Radio sits in the top tank compartment. 28 mile journey to work and back, in a fairly built up journey no loss of DAB signal for the entire journey... so a good result
( no extrernal speakers so no looking like a div when parked at lights :laugh:)
I use one of these. They're fantastic.http://www.amazon.co.uk/Scala-Motorcycle-Intercom-Bluetooth-Handsfree/dp/B0013V3Q56/ref=sr_1_1?ie=UTF8&qid=1374698626&sr=8-1&keywords=cardo+scala+q2
