I have a THB TrendTalk car kit for Treo 600 for sale. The kit has connector for hardwire installation, but I will include a cigarette lighter adapter (from Fry's) that I used to power it in my SAAB. I bought this, and tried it in my SAAB 9-5. It works, but I just couldn't find a decent place to mount the kit in my car, so I am selling it. I have no manual for this either. Pleas PM me or email me with offers or questions. The TreoCentral store sells this for $189.95.
