Is the kit out of those two that I would get. So far I have had one CF-30 GPS and one CF-29 GPS kit from him with out problem. ( I also have two CF-31 kits I have yet to install)

The kit with the larger board is to fully replace the daughterboard on the 19, the other one just plugs and plays like the original style GPS.

I have/had several 19's with GPS and will be upgrading my Mk3 with GPS soon.

He is also on ebay, eBay My World - custom-toughbooks

I have a full review on here when I installed my unit on my 29.

I have contacted him with questions before and always got a quick reply.

 

I can vouch for the CF-19 GPS from TechTuff. I have one in my mk3, works great. The hole to squeeze the connector through is REALLY tight, so be patient and go slow.
