So I bought this Cellink BTG-7000 Bluetooth GPS
receiver for less than $39.00 from Geeks.com
and have been using it for two days now with Blackberry Maps on my 8700g with 18.104.22.1686 OS and it is great!
I put a quick review on my blog
but I will be doing a little more testing this weekend. If anyone wants me to check anything out, please reply to this post and I will try and accommodate.
Overall, it's a great GPS receiver for the money... SPECS from Cellink-eu.com
